Abstract:
The work embodied in this thesis was carried out by the author in the Department of Applied Chemistry, CUSAT, Kochi, during the period 2008-2013. The thesis brings to light, our attempts to evaluate the coordination behavior of some compounds of interest. The biological activities of semicarbazones and their metal complexes have been an active area of research during the past years because of their significant role in naturally occurring biological systems. Tridentate NNO and ONO semicarbazone systems formed from heterocyclic and aromatic carbonyl compounds and their transition metal complexes are well-authenticated compounds in this field and their synthesis, crystal structures and spectral studies are well desirable. Hence, we decided to develop a research program aimed at the syntheses, crystal structures and spectral studies of copper complexes with halides and pseudohalides. In addition to single crystal X-ray diffraction studies, various physico-chemical methods of analysis were also used for the characterization of the complexes

Abstract:
The thesis is an introduction to evaluate the coordination behaviour of a few
compounds of our interest. The crucial aim of these investigations was to
synthesize and characterize some transition metal complexes using the ligands
benzaldehyde, 2-hydroxybenzaldehyde and 4-methoxybenzaldehyde N(4)-ring
incorporated thiosemicarbazones.The study involves a brief foreword of the metal
complexes of thiosemicarbazones including their bonding, stereochemistry and
biological activities.The different analytical and spectroscopic techniques used for
the analysis of the ligands and their complexes are discussed.It also deals with the synthesis and spectral characterization of the
thiosemicarbazones and single crystal X-ray diffraction study of one of them.Chapter 3 describes the synthesis, spectral characterization, single crystal X-ray
diffraction studies of copper(ll) complexes with ONS/NS donor
thiosemicarbazones. Chapter 4 deals with the synthesis, spectral characterization
and single crystal X-ray diffraction studies of nickel(II) complexes. Chapter 5
contains the synthesis, structural and spectral characterization of the cobalt(III)
complexes. Chapters 6 and 7 include the synthesis, structural and spectral
characterization of zinc(II) and cadmium(ll) complexes with ONS/NS donor
thiosemicarbazones.
