Abstract:
The present work deals with the complexation of Schiff
bases of aroylhydrazides with various transition metal ions. The hydrazone
systems selected for study are capable of forming bridged polymeric structures
which is one of the fascinating subjects in the crystal engineering of coordination
polymers owing to their attractive new topologies and intriguing structural
features. Complexation with metal ions like copper, manganese, vanadium,
nickel, palladium, zinc and cadmium are tried. Various spectral techniques are
employed for characterization. The structures of some complexes have been well
established by single crystal X-ray diffraction studies.The work is presented in seven chapters and the last section deals with
summary and conclusion. The studies reveal that the aroylhydrazone systems vary
in their geometrical configuration depending on the substituents. The coordination
modes of the ligands also differ upon chelating with metal ions. One of the
hydrazone system selected for study proved that it could give rise to polymeric
metal complexes.
