| Abstract: | Abstract
Coordination compounds play vital roles in biology, biochemistry and medicine,
controlling the structure and function of many enzymes and their metabolism. They
find varied application in many industrial processes and in the development of new
materials with specifically designed properties. Thus, synthesis and study of the
complexes is very important. In this project work, equimolar quantities of ophenyldiamine
and ninhydrine were condensed to produce a quionoxline derivative
(NHOPD) which behaves as a bidentate ON donor ligand. The formation of
quionoxline derivative (NHOPD) was confirmed by 1HNMR. The ligand (NHOPD)
was further complexed with divalent Ni (II) and Co (II) metal salts. Metal complexes
of nickel and Cobalt with quionoxline (NHOPD) were prepared and characterized
by elemental analysis, conductance measurements, atomic absorption spectra, IR,
NMR and UV spectroscopy and magnetic susceptibility measurements. |
