Structural, Spectral, Biological and Electrochemical Studies Of Some ...

PREFACE
The work embodied in this thesis was canied out by the author in the Department of
Applied Chemistry during 1999-2003. The primary aim of these investigations was
to probe the spectroscopic, electrochemical, biological and single crystal X-ray
diffraction studies of some selected transition metal complexes of 4N_
monosubstituted thiosemicarbazones.
The chemistry of thiosemicarbazones has received considerable attention due to their
proliferate applications. The transition metal complexes of them found applications
in biology, medicine and industry. The present investigation is confined to the
spectral, electrochemical, biological and single crystal X-ray diffraction studies of
Cu(II), V(N), V(V), Fe(III), Mn(II), Ni(II) and Zn(II) complexes of mono anionic
tridentate thiosemicarbazones with O-N-S and N-N-S donor atoms.
The work embodied in the thesis is divided in to nine chapters. Chapter 1 gives a
brief introduction about metal complexes of thiosemicarbazones, including their
structural and bonding properties. Chapter 2 deals with the syntheses and single
crystal X-ray diffraction studies of various thiosemicarbazones used up for the
present investigations and various characterization techniques. Chapter 3 deals with
spectral, biological and electrochemical studies of Cu(II) complexes with N-N-S
donor thiosemicarbazones. Chapter 4 deals with spectral, biological and
electrochemical studies of Cu(II) complexes with O-N-S donor thiosemicarbazones.
Chapter 5 includes spectral, biological electrochemical and single crystal studies of
vanadyl and vanadate complexes. Chapter 6 deals with spectral, biological and
electrochemical studies of low spin Fe(III)complexes. Chapter 7 includes spectral,
biological electrochemical and single crystal X-ray diffraction studies of
Mn(II)complexes. Chapter 8 deals with spectral, biological, (structure activity
relation) electrochemical and single crystal X-ray diffraction studies of Ni(II)
complexes. Chapter 9 includes spectral, and biological studies of Zn(II) complexes.
