This book deals with some modern methods used in the synthesis and characterization of transition metal complexes. It is written primarily to stimulate the interest of students in metallo-organic chemistry and spectroscopy as well. The book is contained much useful spectral data in the form of tables and spectra. It contains a number of electronic, IR and EPR spectra, so the reader who is not familiar with these techniques can see how the spectra actually appear. It begins with a general introduction of applications of transition metal complexes in different fields. In subsequent chapters the detailed study regarding the synthesis and physicochemical characterization of bivalent transition metal ions [Cr(III), Mn(II), Co(II), Ni(II) and Cu(II)] complexes derived from 2-methylcyclohexanone semicarbazone and thiosemicarbazone using modern techniques like elemental analysis, magnetic moments and conductance measurements and spectroscopic (Electronic, IR, EPR ) studies is discussed. The geometry of synthesized complexes is emphasized. The book is intended to be useful to new metallo-organic researchers.

This book focuses on the electronic properties of transition metals in coordination environments. These properties are responsible for the unique and intricate activity of transition metal sites in bio- and inorganic catalysis, but also pose challenges for both theoretical and experimental studies. Written by an international group of recognized experts, the book reviews recent advances in computational modeling and discusses their interplay using experiments. It covers a broad range of topics, including advanced computational methods for transition metal systems; spectroscopic, electrochemical and catalytic properties of transition metals in coordination environments; metalloenzymes and biomimetic compounds; and spin-related phenomena. As such, the book offers an invaluable resource for all researchers and postgraduate students interested in both fundamental and application-oriented research in the field of transition metal systems.
