Book Description
Now a days, coordination chemistry of metal ion complexes with various types of ligands has been a major area of research among the scientists working in the fields of inorganic chemistry. Due to the applicability of such complexes in a diverse range of areas such as industry, research, medical science and numerous other fields, the focus on the designing, synthesize and characterization of coordination complexes is continuously increasing. A special feature of these complexes is that they play vital roles in living and other systems. This is corroborated by the fact that many chemical compounds that are essential components of important substances in living systems (such as enzymes, chlorophylls, haemoglobin) are metal complexes. In fact bioinorganic chemistry has become a bridge between Biological Sciences and Chemical Sciences. This inter relation is proven by the fact that one third of all enzymes have metal ions as constituents

Book Description
The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.

Book Description
There is great interest in metallosupramolecular materials because of their use in magnetic, photonic and electronic materials. Functional Metallosupramolecular Materials focuses on the applications of these materials covering the chemistry underlying the synthesis of a variety of ligands to coordinate various metal ions and the generation of 2D and 3D materials based on these constructs. The book starts by looking at different metallosupramolecular systems including naturally occurring functional metallosupramolecular materials; DNA-based metallosupramolecular materials; metallopolymers; metallogels as well as functional materials based on MOFs. Subsequent chapters then systematically cover the different applications such as molecular computation, spin-crossover, light harvesting and as photocatalysts for the production of solar fuels. The book provides an overview of functional metallosupramolecular materials that will be of interest to graduate students, academics and industrial chemists interested in supramolecular chemistry, materials science and the materials applications.

Book Description
1.1. Introduction of Schiff Bases The development of coordination chemistry significantly enhances from the usage of one of the most well-known families of organic compounds, which are widely employed as synthetic intermediates and chelating ligands for transition and inner transition metals. The research of Schiff bases and related metal complexes has exploded in the last few decades due to their simple hydron-donating property and flexible nature.
