Physico-chemical Studies of Cobalt(II) Complexes Derived from 2-Substituted Benzaldehyde Semicarbazones and Thiosemicarbazones

Abstract

Cobalt(II) complexes with 2-chlorobenzaldehyde/2-ethoxybenzaldehyde semicarbazone and thiosemicarbazone (cbsc, cbtsc, ebsc and ebtsc) have been synthesized and characterized by means of various physico-chemical techniques viz., elemental analysis, magnetic moment, infrared spectral and electronic spectral studies. IR spectral studies showed bidentate chelating behaviour of the ligands coordinating through azomethine nitrogen and carbonyl oxygen/thioketo sulphur atoms. Magnetic moment of these complexes indicates high spin configuration. The probable structure for all the metal complexes is also proposed here.
