Download or read book On Being Well-coordinated: A Half-century Of Research On Transition Metal Complexes written by John L Burmeister and published by World Scientific. This book was released on 2003-10-14 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: This invaluable book distils the research accomplishments of Professor Fred Basolo during the five decades when he served as a world leader in the modern renaissance of inorganic chemistry. Its primary focus is on the very important area of chemistry known as coordination chemistry.Most of the elements in the periodic table are metals, and most of the chemistry of metals involves coordination chemistry. This is the case in the currently significant areas of research, including organometallic homogenous catalysis, biological reactions of metalloproteins, and even the solid state extended structures of new materials. In these systems, the metals are of primary importance because they are the sites of ligand substitution or redox reactions. In the solid materials, the coordination number of the metal and its stereochemistry are of major importance.Some fifty years of research on transition metal complexes carried out in the laboratory of Professor Basolo at Northwestern University is recorded here as selected scientific publications. The book is divided into three different major research areas, each dealing with some aspect of coordination chemistry. In each case, introductory remarks are presented which indicate what prompted the research projects and what the major accomplishments were. Although the research was of the academic, curiosity-driven type, some aspects have proven to be useful to others involved in projects that were much more applied in nature.

Book Synopsis Variety in Coordination Modes of Ligands in Metal Complexes by : Shinichi Kawaguchi
Download or read book Variety in Coordination Modes of Ligands in Metal Complexes written by Shinichi Kawaguchi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal complexes play important roles as catalysts or other participants in synthetic and biological reactions. Substrates and sometimes attacking reagents also are activated through coordination with metal atoms or ions. In these events the natures not only of the central metals but also of ancillary ligands exert important influences on the stability and reactivity of the coordinated substrates. A ligand in general can adopt various coordination modes depending on its chemical environment, thus functioning as a probe. The number of coordination modes increases with increasing complexity of the ligand. In this book it is shown that even the simplest mono- and diatomic ligands such as H, CO, and N2 exhibit a variety of coordination modes, which are related to their reactions. The thiocyanate anion is taken up as a representative of the triatomic ambidentate ligands, and factors influencing the preferences for N- und S-bonding are summarized. Coordination chemistry of ß-dicarbonyl compounds is a highlight of this book. Acetylacetone, one of the most familiar Werner ligands, is shown to favor -carbon and n-allylic bonding in many instances. Its versatile behaviour in changing coordination modes is revealed.

Book Synopsis Main Group and Transition Metal Complexes Supported by Carbon, Sulfur, and Selenium Donor Ligands by : Patrick Quinlivan
Download or read book Main Group and Transition Metal Complexes Supported by Carbon, Sulfur, and Selenium Donor Ligands written by Patrick Quinlivan and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For example, a mixture of [TmBut]ZnMe and Me2Cd form an equilibrium mixture with [TmBut]CdMe and Me2Zn. Furthermore, transfer of the [TmBut] ligand between the metal centers is possible too. This is demonstrated by the transfer of [TmBut] from mercury to zinc in the methyl system, [TmBut]HgMe/Me2Zn. Additionally, transfer of [TmBut] from zinc to mercury is also observed upon treatment of [TmBut]2Zn with HgI2 to afford [TmBut]HgI and [TmBut]ZnI, thereby indicating that the nature of the co-ligand has a profound effect on the thermodynamics of ligand exchange. Chapter 3 explores the coordination chemistry of the selenium donor ligand, H(sebenzimMe). H(sebenzimMe) is able to coordinate metal centers through the selenium atom in a dative fashion, and, depending upon the metal center, up to four H(sebenzimMe) ligands can coordinate the same metal. Additionally, H(sebenzimMe) can be deprotonated to form [sebenzimMe]–, allowing for the potential of an LX coordination mode, which results in bridging complexes for the metal compounds investigated.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen based monodentate and bidentate chelating ligands have captured a significant interest due to their ability to coordinate to a wide variety of elements. The â-diketimine, â-ketoiminato, formamidine, pyridineselenolate, and pyrazinecarboxamide ligands have all been employed in this study to further investigate the coordination preferences among main group and transition metals. Steric and electronic properties of these ligands can easily be altered by manipulating the substituents attached, thus leading to predictable structures with potential for many useful and significant applications. Investigations have shown that temperature, solvent, and metal halide employed are all key factors in the reaction outcomes. All of the complexes obtained throughout these studies have been characterized by X-ray crystallography along with other spectroscopic techniques, including NMR, IR, UV/Vis, and M/S. â-diketiminato ligands, [{N(R)C(Me)}2C(H)] where R = Dipp, Mes, commonly referred to as nacnac, have played an important role in the synthesis of novel pnictogenium complexes. Results show that through manipulation of the halide precursor, reaction stoichiometry, and the R substituent on the nacnac both N, N'- and N, C'-metal chelated complexes can be achieved. Additionally, â-ketiminato ligands, [RN(H)(C(Me))2C(Me)=O] where R = Dipp, and [RN(H)C(Me)CHC(Me)=O] where R = C2H4NEt2, have been studied. Both ligands were investigated with a range of d and p block metal halides and alkyls in order to compare and contrast the bulky, flexible, and even multi-dentate nature of each ligand. The preferred metal geometry remains constant for products with either ligand, but the steric protection offered by the individual ligands governs the nuclearity of the products, ranging from tetrameric cages to simple adducts. The formamidinate ligand, [RN(H)C(H)NR] where R = Dipp, was employed in synthesizing several aluminum and zinc complexes. In addition to their numerous applications as cata.

This book was released on 2014 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Nature, transition metal-containing enzymes have evolved to catalyze a wide variety of chemical reactions with astounding efficiencies and selectivities through precise control of their primary and secondary coordination environments. Taking inspiration from the active sites of metalloenzymes, synthetic bioinorganic chemists have endeavored to construct metal complexes that model the structures and functions of these enzymes. Controlling the primary coordination spheres of metal ions to model active sites is accomplished through the construction of metal-binding organic ligand frameworks, but the resulting metal complexes often lack the activities observed in their biological counterparts. Non-covalent secondary coordination sphere effects that are present within metalloenzyme active sites are integral to the proper function of these proteins and have been more challenging to emulate within synthetic systems. Manipulation of the secondary coordination environment surrounding synthetic metal complexes can be accomplished by using rigid ligand scaffolds containing groups that promote non-covalent interactions proximal to the metal center. The Borovik group has developed a number of tetradentate ligands that can bind metal ions and establish a pocket where external ligands can bind to the metal center. The ligands contain moieties that interact with the metal-bound exogenous ligands through non-covalent effects, particularly hydrogen bonds (H-bonds). This dissertation chronicles the advances made with two tripodal ligand platforms that promote intramolecular H-bonding networks within the resulting complexes. The first ligand studied, TAO, tautomerizes upon metal ion binding to provide a neutral N4 primary coordination environment to the metal center. This tautomerization event places H-bond donating groups proximal to external ligands that can bind to the metal center, producing intramolecular H-bonding networks. TAO complexes are sufficiently flexible to accommodate ligands of varying sizes, shapes, and charges. The versatility of the TAO framework is exemplified through a series of metal complexes which have been characterized in both the solution and solid state. Ab initio theoretical calculations performed on many of these complexes provide insight into the electronic effects of the H-bonding interactions. The ligand [MST]3 binds metal ions in a similar manner to TAO, but possesses sulfonamido groups that render the complex cavity capable of both accepting H-bonds and binding secondary metal ions. The bifunctionality of [MST]3 has been explored through the synthesis of heterobimetallic complexes wherein the metal ions are bridged by a hydroxido group. The work on [MST]3 in this dissertation focuses on diamagnetic main group analogs of these complexes whose structures could be elucidated in both the solution and solid states. The structurally characterized complexes were found to retain their supramolecular structures in solution. The relevance of some of these complexes to the oxygen evolving complex within Photosystem II is also discussed. Additionally, M-NH3 (M = Fe11, Fe111, Ga111) complexes are presented that contain intramolecular H-bonding networks and which remain assembled in both solution and the solid state. A putative Fe111-NH2 species and its reactivity is discussed, and the synthesis and structure of a Ga111-N2H4 complex is documented. A new N4 donor ligand platform, [POAT]3− is presented in the final portion of this dissertation. In complexes with this ligand, phosphine oxide groups are positioned within the secondary coordination sphere of the metal center to act as H-bond acceptors and to bind additional metal ions. While these features are akin to those in the [MST]3 system, preliminary studies indicate that the primary coordination sphere is much more reducing; as such, complexes with [POAT]3− are anticipated to stabilize metal complexes in higher oxidation states.
