Solid State Structural, Catalytic and Physico-chemical Elucidation of VO(IV), Pt(IV) and Ce(IV) Coordinated Compounds of Schiff Bases

Abstract

Pt(IV), VO(IV) and Ce(IV)-complexes of the Schiff bases, viz., 2-(phenylthio) anilimino-4- chloro benzylidene (PACB), 2-(phenylthio) anilimino-4-chloro-3-nitro benzylidene (PACNB) and 2-(phenylthio) aniliamino-4-methoxy benzylidene (PAMB) have been synthesized and characterized by elemental analyses, molar conductance, electronic, infrared spectra, ¹H NMR, ESR, thermal and magnetic susceptibility measurements. Synthesized complexes have been tested for their reactivity and substitution behaviour. All the ligands behave as bidentate, coordinating through O and N atoms. The proposed geometry for the complexes is square-pyramidal. Conductivity studies reflect the semi-conducting behaviour of the complexes.
