This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterometallic oxides are used as materials in many applications, e.g. from ferroelectrics to superconductors. Making these compounds usually requires high temperatures and long reaction times. Molecular precursors may contribute to render their processing shorter and accessible at lower temperatures, thus cheaper in energy and time. In this review article, different approaches toward oxide materials will be shown, starting with homometallic clusters and coordination polymers and highlighting recent results with heterometallic single source precursors. On the way to the latter, we came across many exciting results which themselves allowed applications in different fields. This work will give an overview on how these fields were brought together for the current mixed metallic compounds as precursors for heterometallic oxides.
Book Synopsis Tunable Synthesis and Properties of Preyssler-Based Coordination Networks by : Linfeng Chen
Download or read book Tunable Synthesis and Properties of Preyssler-Based Coordination Networks written by Linfeng Chen and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assembly of metal oxide clusters with metal linkers offers a route to new metal oxide framework materials that bridge the gap between metal organic frameworks and zeolites. Such materials offer advantages over traditional bulk or nanocrystalline doped metal oxides because the atom placement is precisely defined. The use of these all inorganic frameworks as functional materials, however, remains largely unexplored. Recently, a new type of all-inorganic network material has been developed by using polyoxometalates (POMs). POMs exhibit great properties in the field of redox chemistry, hydrolyzable protons and anionic and oxygen-rich nature. Among all POMs, Preyssler cluster is one of the most attractive metal oxide clusters because of its easy preparation, stability in a wide pH range (0-11) and great electroactive properties. In Chapter2, the general experimental methods have been introduced. The basic synthetic design are shown by figures and words. In Chapter 3, I present the synthesis of metal oxide frameworks comprised of [NaP5W30O110]14- assembled with Mn, Fe, Co, Ni, Cu or Zn bridging metal ions. X-ray diffraction shows that the frameworks adopt the same assembly regardless of bridging metal ion. Furthermore, our synthesis allows for the assembly of isostructural frameworks with mixed-metal ion bridges, or with clusters that have been doped with Mo, providing a high degree of compositional diversity. This consistent assembly enables investigation into the role of the building blocks in the properties of the metal oxide frameworks. The presence of bridging metal ions leads to increased conductivity compared to unbridged frameworks, and frameworks bridged with Fe have the highest conductivity. Additionally, Mo-doping can be used to enhance the conductivities of the frameworks. Similar structures can be obtained from clusters in which the central Na+ has been replaced with trivalent cations Bi3+ or Sm3+. Overall, the optical and electronic properties are tunable via choice of bridging metal ion and cluster building block and reveal emergent properties in these cluster-based frameworks. These results demonstrate the promise of using polyoxometalate clusters as building blocks for tunable complex metal oxide materials with emergent properties. In Chapter 4, I present the use of the Preyssler polyoxoanion, [NaP5W30O110]14- ({P5W30}), as a platform for evaluating the role of cations on the assembly of transition-metal-bridged polyoxometalates (POMs) into coordinatively linked frameworks. Specifically, we show that the assembly architecture of Co2+-bridged {P5W30} frameworks is dependent on the identity and amount of alkali or alkaline earth cations present during crystallization. The inclusion of Li+, Na+, K+, Mg2+ or Ca2+ in framework synthesis is used to selectively synthesize five different Co2+-bridged {P5W30} structures. We evaluate the role of the competition between K+ and Co2+ for binding to {P5W30}. Furthermore, we show that anions that are not incorporated into the framework structure indirectly impact this balance by competing for K+ during crystallization. The role of ion-pairing on framework assembly structure and available porosity are discussed. Overall, these results provide insight into factors governing the ability to achieve controlled assembly of POM-based coordination networks. In Chapter 5, I present the use of a modified Preyssler anion, [NaP5MoW29O110]14- ({P5MoW29}), as a platform for understanding the process of photoreduction in the metal oxide. The frameworks can be photoreduced by sunlight, allowing the storage of electrons under mild conditions. Titration with the molecular redox species shows that this reduction is reversible without changing the crystal structure. Remarkably, the Zn2+-bridged {P5MoW29} can maintain their reduction status over six months, suggesting the unique structure stability. These results demonstrate that the polyoxometalate self-assembly frameworks can be an excellent material to understand the process of photo-electron transportation and develop new metal oxides with emergent properties. In Chapter 6, Single-crystal-to-single-crystal (SCSC) transformations have received considerable interest in crystal engineering, providing a key platform for creating new materials and understanding chemical reactions and mechanisms. We synthesize a new metal oxide framework based on a modified Preyssler ion, linked with Ln3+, for understanding the process of SCSC transformations with an atomic characterization from the initial cluster and transition state to the final extended network.in the metal oxide. By tracing the labeled center ions of crown-type Polyoxometalate, Preyssler ion, in the crystal-grown process, a direct, comprehensive, visible SCSC transformation is confirmed. The post-synthetic method was used to synthesize sites precisely controlled Bi/Tri-Ln coordination networks. Overall, these results provide insight into factors influencing SCSC transformations during the crystallization process and offer a new pathway to new precise solid-state materials.

Book Synopsis Ligand Field Theory and Its Applications by : Brian N. Figgis
Download or read book Ligand Field Theory and Its Applications written by Brian N. Figgis and published by Wiley-VCH. This book was released on 2000 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete, up-to-date treatment of ligand field theory and its applications Ligand Field Theory and Its Applications presents an up-to-date account of ligand field theory, the model currently used to describe the metal-ligand interactions in transition metal compounds, and the way it is used to interpret the physical properties of the complexes. It examines the traditional electrostatic crystal field model, still widely used by physicists, as well as covalent approaches such as the angular overlap model, which interprets the metal ligand interactions using parameters relating directly to chemical behavior. Written by internationally recognized experts in the field, this book provides a comparison between ligand field theory and more sophisticated treatments as well as an account of the methods used to calculate the energy levels in compounds of the transition metals. It also covers physical properties such as stereochemistry, light absorption, and magnetic behavior. An emphasis on the interpretation of experimental results broadens the book's field of interest beyond transition metal chemistry into the many other areas where these metal ions play an important role. As clear and accessible as Brian Figgis's 1966 classic Introduction to Ligand Fields, this new book provides inorganic and bioinorganic chemists as well as physical chemists, chemical physicists, and spectroscopists with a much-needed overview of the many significant changes that have taken place in ligand field theory over the past 30 years.

Book Synopsis Heteropoly and Isopoly Oxometalates by : Michael Pope
Download or read book Heteropoly and Isopoly Oxometalates written by Michael Pope and published by Springer. This book was released on 2013-01-14 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combined oxygen, in the form of water, metal oxides, silicates and other oxyions, accounts for about 50% by weight of the earth's crust. The chemistry of this most abundant element has two major aspects: that of water and aqueous solutions of electrolytes, and that of the solid state. The methodology and techniques appropriate for the study of these fields are sufficiently different that there have been very few points of contact between solution- and solid state chemists. One such contact, of great potential value, is provided by the extensive class of polyoxoanions formed by the transition metals of groups 5 and 6. As 'heteropoly and isopoly acids' these polyanions have been known and investigated for more than a century. The pre sent book is an attempt to survey the chemistry, structures, and applications of these species. Although the book forms part of a series in inorganic chemistry, the field of polyoxometalates deserves wider attention, for example, from organic chemists, especially those concerned with homogeneous and heterogeneous catalysis, and from biochemists, solid state- and materials scientists.
Book Synopsis Cage Metal Complexes by : Yan Voloshin
Download or read book Cage Metal Complexes written by Yan Voloshin and published by Springer. This book was released on 2017-05-11 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fundamental book presents the most comprehensive summary of the current state in chemistry of cage metal complexes. After their previous book “The Encapsulation Phenomenon” (www.springer.com/978-3-319-27737-0) the authors in this book focus on the encapsulation of metal ions by different types of three-dimensional mono- and polynucleating caging ligands. Within these cage metal complexes, (metal) ions can be isolated from external factors. The book provides both a classification of the cage compounds and summaries of synthetic approaches. On that basis the authors then describe the unique chemical and physical properties and the resulting reactivity of the cage compounds, as well as practical and potential applications as potent topological drugs and prodrugs, antifibrillogenic agents, radiodiagnostic and radiotherapeutic compounds, paramagnetic probes, single-molecule magnets, electrocatalysts for hydrogen production, (photo)electronic devices, and many more. Readers will find a well-structured and concise overview, with particular emphasis on a review of synthesis and reactivity of various cage metal complexes, summarizing over 400 literature references, clearly presented in over 300 color schemes and figures.
Book Synopsis Nanostructured Catalysts by : Susannah L. Scott
Download or read book Nanostructured Catalysts written by Susannah L. Scott and published by Springer Science & Business Media. This book was released on 2008-04-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the recent advent of nanotechnology, research and development in the area of nanostructured materials has gained unprecedented prominence. Novel materials with potentially exciting new applications are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured materials join forces to provide insightful reviews of their areas of expertise, thus offering an overall picture of the state-- the art of the field. Nanostructured materials designate an increasing number of materials with designed shapes, surfaces, structures, pore systems, etc. Nanostructured materials with modified surfaces include those whose surfaces have been altered via such techniques as grafting and tethering of organic or organometallic species, or through various deposition procedures including electro, electroless and vapor deposition, or simple adsorption. These materials find important applications in catalysis, separation and environmental remediation. Materials with patterned surfaces, which are essential for the optoelectronics industry, constitute another important class of surface-modified nanostructured materials. Other materials are considered nanostructured because of their composition and internal organization.
