The book provides detailed understanding of materials for stability, synthesis and catalytic activities of metal complexes that form important part of inorganic chemistry for the undergraduate and postgraduate students of most universities besides all entrance examinations of India such as CSIR-NET, GATE, NTPC, DRDO, pre-Ph.D. etc. Metal complexes are an integral part of the inorganic chemistry and extremely useful for researchers to develop industrial products. This textbook is a blend of all the important concepts of metal complexes based topics such as Advance Nomenclature of Coordination Compounds, lsoelectronicity and lsolobal Analogy, Electron Rules, Spectral Studies of Metal Complexes, Organometallic Complexes etc. It is primarily designed to cover the syllabi of most Indian universities and also develop conceptual understanding of metal complexes. Special features • The information regarding inorganic reaction pathways, catalytic activities and industrial uses are explained within the frame work of concepts and 3D structures in 2D manners, which help students to organize and understand inorganic metal complexes. • All of the printed chemical formulas convey stereochemistry followed by its point group's information. The stability of metal cluster defined by electron rules and its spectral data are added in this book. • Including interpretative discussion of constructive reactions for the cluster synthesis, reactivity and catalytic activities for furnishing many organic species, provides a reasonable understanding in students. • A large number of well illustrated line diagrams are given along with the text and the data is presented in the numerous forms for references and comparisons. • Includes more exercises and problems based on the questions asked in many universities and competitive examinations.
