Whereas other N2S2 metalloproteins function in catalytic roles, zinc fingers serve mostly a structural element, although there has been some evidence that the zinc finger protein can interact with exogenous metal ions in aggregate formation or ion exchange. The work presented within has been aimed at precedents for both of the latter in Zn2. The use of zinc and cadmium dithiolate complexes as mono- and bidentate S-donor ligands to tungsten carbonyl complexes was explored and the ability of zinc and cadmium complexes to stably bind to W(CO)x (x = 4 and 5) was established. The reactivity of thiolate sulfurs within the bimetallic complexes was examined, gaining an understanding of zinc and cadmium N2S2. The characteristics of these complexes were examined via IR, UV-vis, elemental analysis, and x-ray crystallography spectroscopy. The ability of zinc to act as a scaffold for the synthesis of bisacetylbme-dach in the production and subsequent transfer of the same ligand to exogenous metal ion sources was investigated. Cu2 and Cd2+ analogs to the Zn-1'-Ac2 were synthesized and their properties investigated with IR, elemental analysis, and UV-vis spectroscopy.

Available in PDF, EPUB and Kindle. Book excerpt: In September 2002, a NATO-ASI was held in Cetraro (CS), Italy on the theme of "Metal-Ligand Interactions in Molecular-, Nano-, Micro-, and Macro-systems in Complex Environments". This event has followed the previous ones held in the same place in 1991, 1994 and 1998. In the present and the previous schools a broad interdisciplinary cross-section of experimental and theoretical researchers, interested in a better understanding of metal-ligand interactions from different viewpoints, was linked together to exchange experience, to review the state-of-the-art, to indicate new techniques and methods, to explore new fields and perspectives. Particular emphasis was given to the problems related with the crossing from molecular systems to nano-, macro-and micro-scale materials and to the effects of the environment on the properties of the molecular systems. The school was organized around lectures and special research seminares given by leading experts in the following fields: • metal clusters • inorganic complexes and materials • surface phenomena • adsorption and catalysis • organic and bio-inorganic systems • ab initio theory • density functional theory • classical and quantum dynamics This volume contains the formal lectures and selected contributed papers and describes the main aspects and problems tackled during the 12 days of the event.

This book was released on 2012-12-06 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal-ligand interactions are currently being studied in different fields, from a variety of points of view, and recent progress has been substantial. Whole new classes of compounds and reactions have been found; an arsenal of physical methods has been developed; mechanistic detail can be ascertained to an increasingly minute degree; and the theory is being developed to handle systems of ever-growing complexity. As usual, such multidisciplinarity leads to great opportunities, coupled with great problems of communication between specialists. It is in its promotion of interactions across these fields that Metal-Ligand Interactions: From Atoms, to Clusters, to Surfaces makes its timely contribution: the tools, both theoretical and experimental, are highly developed, and fundamental questions remain unanswered. The most fundamental of these concerns the nature of the microscopic interactions between metal atoms (clusters, surfaces) and ligands (atoms, molecules, absorbates, reagents, products) and the changes in these interactions during physical and chemical transformation. In Metal-Ligand Interactions, leading experts discuss the following, vital aspects: ab initio theory, semi-empirical theory, density functional theory, complexes and clusters, surfaces, and catalysis.

Book excerpt: Volume 17, entitled Lead: Its Effects on Environment and Health of the series Metal Ions in Life Sciences centers on the interrelations between biosystems and lead. The book provides an up-to-date review of the bioinorganic chemistry of this metal and its ions; it covers the biogeochemistry of lead, its use (not only as gasoline additive) and anthropogenic release into the environment, its cycling and speciation in the atmosphere, in waters, soils, and sediments, and also in mammalian organs. The analytical tools to determine and to quantify this toxic element in blood, saliva, urine, hair, etc. are described. The properties of lead(II) complexes formed with amino acids, peptides, proteins (including metallothioneins), nucleobases, nucleotides, nucleic acids, and other ligands of biological relevance are summarized for the solid state and for aqueous solutions as well. All this is important for obtaining a coherent picture on the properties of lead, its effects on plants and toxic actions on mammalian organs. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 17, which are written by 36 internationally recognized experts from 13 nations. The impact of this recently again vibrant research area is manifested in nearly 2000 references, over 50 tables and more than 100 illustrations (half in color). Lead: Its Effects on Environment and Health is an essential resource for scientists working in the wide range from material sciences, inorganic biochemistry all the way through to medicine including the clinic ... not forgetting that it also provides excellent information for teaching.

This book was released on 1997 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the final report of a three-year Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). At the forefront of chemistry are efforts to catalytically transform the inert C-H bonds in alkanes to more useful products using metal compounds. The goal is to observe binding and cleavage of alkane C-H bonds on metals or to use related silane Si-H bonding as models, analogous to the discovery of hydrogen (H2) binding to metals. Studies of these unique sigma complexes (M{hor_ellipsis}H-Y; Y{double_bond}H, Si, C) will aid in developing new catalysts or technologies relevant to DOE interest, e.g., new methods for tritium isotope separation. Several transition metals (Mo, W, Mn, and Pt) were found to reversibly bind and cleave H2, silanes, and halocarbons. The first metal-SiH4 complexes, thus serving as a model for methane reactions. A second goal is to study the dynamics and energetics of H-Y bonds on metals by neutron scattering, and evidence for interactions between bound H-Y and nearby H atoms on metal complexes has been found.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interactions between main group elements and d- and f-block metals are important in many chemical applications. Calculated bond dissociation energies (BDE) and heats of formation of the Group 3 metal halide dimers (MX, where M = Sc, Y, La and X = F, Cl, Br, I) for the X1ÎĐ+ and a3Îþ state were used to explain the chemiluminescent reactions of the Group 3 metals Sc and Y with F2, Cl2, Br2, ClF, ICl (Sc), IBr (Y) and SF6 and La with F2, SF6, Cl2, and ClF and show that the observed spectra are due to metal monohalide emission. The BDE calculations were performed using the Feller-Peterson-Dixon (FPD) approach including molecular spin-orbit (SO) corrections. The initial steps in the selective catalytic reduction (SCR) of NO by TiO2 supported vanadium oxides and surface adsorbed NH3 were predicted at the density functional theory (DFT) level with the B3LYP functional benchmarked at the coupled cluster CCSD(T) level. Different proton transfer pathways which depend on the initial neutral or protonated sites coupled with addition of NO lead to formation of a NH2NO surface species and reduction of a vanadium and spin transfer to the metal oxide surface. NH2NO subsequently desorbs and decomposes in the gas phase following a series of intramolecular rearrangements with barriers comparable to its generation on the surface. Spectroscopic observation of surface adsorbed NH3 and NH4+ in the SCR reaction is supported by vibrational frequency calculations. However vanadium bound NH2 is not predicted to be present in significant amounts, consistent with experiment. NO2 may also be present in combustion gas streams with the NO so the interactions of NO2 with cluster models of vanadium oxides and supported vanadium oxides were studied at the CCSD(T)//B3LYP level. A qualitative covalent vs, ionic bonding model is further developed, and the key factors in the favorability of nitrate formation on vanandium oxides are proposed. Calculations predict that saturating the vanadia with V-O bonds strengthens the V=O bond, raises the excitation energy, and precludes NO2 chemisorption so that only weak physisorption will occur. A series of organic ligands is investigated for metal selectivity in the separation of actinides (An) from lanthanides (Ln) at the DFT level couples with self-consistent reaction field calculations using the COSMO parameters to predict free energies in aqueous and organic solvents. A novel ligand to metal charge transfer in Eu complexes is predicted.

Book excerpt: Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973
