Book Synopsis Synthesis and Characterisation of 3d-4f-complexes and Their Magnetic Properties by : Jürgen Feuersenger
Download or read book Synthesis and Characterisation of 3d-4f-complexes and Their Magnetic Properties written by Jürgen Feuersenger and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the syntheses of 3d-4f-metal complexes starting from preformed compounds of Mn, Fe and Co, lanthanide salts and organic ligands and also the investigation of their structures and properties. 41 new polynuclear heterometallic metal complexes were synthesised in the course of this work with different interesting properties. The structures of all obtained compounds have been confirmed using X-ray diffraction. The magnetic properties of 22 complexes were studied, of which four show frequency dependent out-of-phase signals as expected for SMMs. The catalytic activity of calcinated {Mn4Dy6Li2} was investigated and proved effective for the oxidation of CO. It was established, that the use of precursors leads to new families of compounds. Moreover the study of isostructural compounds across the lanthanide series showed 1) that the incorporation of 4f ions introduces magnetic anisotropy and 2) DyIII is usually the best candidate for targeting 3d-4f-SMMs.

Download or read book Synthesis of 4f and 3d-4f Homo and Heterometallic Complexes: written by Munendra Yadav and published by Cuvillier Verlag. This book was released on 2015-03-27 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term “lanthanide” was introduced by Victor Goldschmidt with the name of its first element “lanthanum”.1It has the outer electronic configuration 6s25d14f0, so it can either be considered as a d-block elements or an f-block element. The relative energy of the 5d and 4f orbitals are very similar and sensitive to occupancy of orbitals but on the basis of stability of 4f shell which is slightly more compare to 5d shell, it was considered as f-block element. This criterion was followed by next 14 elements and electrons enter in the 4f shell until at lutetium.2The lanthanides are 15 elements in the periodic table considered as the first f-block elements, starting from lanthanum (59La) to lutetium (71Lu), which are commonly referred as “rare earth metals” along with scandium and yttrium. They are chemically represented by the symbol “Ln”.

Available in PDF, EPUB and Kindle. Book excerpt: The thesis is devoted to the synthesis of homo- and heterometallic 3d-metal complexes with Schiff base ligands or derivatives of 1,2,4,5- tetrazine, together with the investigation of their structural and physico-chemical properties. This work can be divided in three parts. In the first part we have been mainly focused on the Schiff base ligands, derivatives of the salicylaldehyde and aminoalcohols. Thirteen heterometallic complexes were obtained and fully characterized. It has been shown that the synthesized compounds possess catalytic activity in the photochemical water oxidation, exhibit photoconducting properties in polymeric composites and can be used for the development of multifunctional materials of wide use. The second part describes the functionalization of Schiff base ligands by the introduction into their structure of electroactive tetrathiafulvalene and dithiolate moieties. Two new families of ligands were synthesized and characterized. The series of radicalcation salts and homo- and heterometallic dithiolene complexes together with the investigation of their physical properties have been described. The last part is devoted to the tetrazine based ligands. The main advantages of the tetrazine ring have been discussed. Two new ligands, derivative of picolylamine and their mono- and binuclear 3d-metal complexes are reported. In conclusion, perspectives of further research related to the described results were highlighted.

Book Synopsis Principles and Applications of Density Functional Theory in Inorganic Chemistry II by : N. Kaltsoyannis
Download or read book Principles and Applications of Density Functional Theory in Inorganic Chemistry II written by N. Kaltsoyannis and published by Springer. This book was released on 2004-08-19 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is difficult to overestimate the impact that density functional theory has had on computational quantum chemistry over the last two decades. Indeed, this period has seen it grow from little more than a theoreticalcuriosity to become a central tool in the computational chemist s armoury. Arguably no area of ch- istry has benefited more from the meteoric rise in density functional theory than inorganic chemistry. the ability to obtainreliable results in feasible ti- scales on systems containing heavy elements such as the d and f transition - tals has led to an enormous growth in computational inorganic chemistry. The inorganic chemical literature reflects this growth; it is almost impossible to open a modern inorganic chemistry journal without finding several papers devoted exclusively or in part to density functional theory calculations. The real imp- tance of the rise in density functional theory in inorganic chemistry is undou- edly the much closer synergy between theory and experiment than was p- viously posible. In these volumes, world-leading researchers describe recent developments in the density functional theory and its applications in modern inorganic and b- inorganic chemistry. These articles address key issues key issues in both sol- state and molecular inorganic chemistry, such as spectroscopy, mechanisms, catalysis, bonding and magnetism. The articles in volume I are more focussed on advances in density functional methodogy, while those in Volume II deal more with applications, although this is by no means a rigid distinction.

Download or read book Metal Clusters in Catalysis written by Bruce C. Gates and published by Elsevier Publishing Company. This book was released on 1986 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on metal clusters (compounds with metal-metal bonds) has undergone explosive growth and the subject is now perhaps one of the hottest'' topics in organometallic chemistry. The prospect of catalytic applications has motivated a large part of the research mentioned in this book - the long term goal being to exploit the unique properties of metal clusters to prepare catalysts with new activities and selectivities. This is the first book to address the role of metal clusters in catalysis. The coverage is up-to-date and is particularly comprehensive, ranging from molecular chemistry of clusters (synthesis, structure, thermochemistry, reactivity, and homogeneous catalysis) to supported clusters (molecular analogues on polymers, and metal oxides and metals in zeolite cages). Preparation by methods of organometallic surface chemistry and metal atom chemistry and characterization of surface structures by physical methods are highlighted. Concepts unifying metal cluster chemistry and the chemistry of metal surfaces are elucidated. Of particular value to the user will be the cluster and subject indexes. The cluster index is organized in alphabetical order according to the metal.

Download or read book NMR Spectroscopy of Polymers written by R.N. Ibbett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: R.N.IBBETT This book provides a source of information on all major aspects of NMR spectroscopy of synthetic polymers. It represents a deliberate attempt to pull together the numerous strands of the subject in a single comprehensive volume, designed to be readable at every scientific level. It is intended that the book will be of use to the vast majority of polymer scientists and NMR spec troscopists alike. Readers new to NMR will find extensive information within the book on the available techniques, allowing full exploration of the many polymer science applications. Readers already established within a branch of NMR will find the book an excellent guide to the practical study of polymers and the inter pretation of experimental data. Readers who have specialised in polymer NMR will find the book a valuable dictionary of proven methodologies, as well as a guide to the very latest developments in the subject. Workers from all of the main branches of polymer NMR have been invited to contribute. Each chapter therefore contains information relating to a parti cular investigative topic, indentified mainly on the basis of technique. The book is loosely divided between solution and solid-state domains, although the numerous interconnections confirm that these two domains are parts of the same continuum. Basic principles are explained within each chapter, combined with discussions of experimental theory and applications. Examples of polymer investigations are covered generously and in many chapters there are discussions of the most recent theoretical and experimental developments.
