ABSTRACT:
A mononuclear cobalt (II) complexes were synthesized from chloro-substituted benzaldehyde derivatives of (N”-[(1Z,2E)-(hydroxyimino)-1-phenylpropylidene]thiocarbonohydrazide (HPTCHOPD) and characterized by magnetic, spectroscopic and electrochemical techniques and by powdered x-ray diffraction. The ligand HPTCHOPD has been reported to give complexes with various metal ions known to coordinate through the oxygen or nitrogen atoms of oximino function andthe imino atoms of the thiocarbohydrazide moiety in this ligand. Whereas thione sulfur of HPTCHOPD is not takes part in coordination with metal ion and found ligand is in thiol form. The aim being to investigate the behaviour of thione sulfur coordination in chloro-substituted benzaldehyde derivatives of HPTCHOPD. The infrared and electronic spectra indicates non-involvement of thione sulfur coordination with Co(II) ion. The molecular weight determination, infrared spectra, electronic spectra, and room temperature magnetic susceptibility measurements proposedmonomeric square planar geometry. The powdered X-ray crystallography study reveals orthorhombic crystal system for these complexes. The energy optimised structures are proposed using the semi empirical quantum mechanical calculations in Argust Lab programme.
