چکیده
Complexes of oxovanadium(lV) with N,N' -ethylene-bis-(2-aminobenzamide) [EBAB], N,N ' -propylene-bis-(2ami nobenzamide) [PBAB], N.N ' -(o-phenylene)-bis-(2-aminobenzamide) [PhBAB] , N,N' -ethylene-bis-(3-carboxypropenamide) [EBCP], N,N' -propylene-bis-(3-carboxypropenamide) [PBCP]and 1-(2'-hydroxyphenyl)-3-phenyl-I ,3-propanedione [HPPPD] have been prepared and characterized by chemical analyses, molar conductivity, magnetic susceptibility measurements. thermal studies, IR. electronic and ESR spectra. Further, de-oxygenation react ions of these complexes with thionyl ch loride yie ld vanadium(lV) complexes. The spectral data reveal that oxovanadium(lV) complexes are square pyramidal while the vanadium(lV) complexes are octahedral.

Bidentate Isatin Schiff Base Ligands Oxovanadium (IV) Complexes
The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.
