|Abstract:||Complexes of oxovanadium(IV) with N,Nʹ -ethylene-bis-(2-aminobenzamide) [EBAB], N,N '-propylene-bis-(2-aminobenzamide) [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-1 ,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 chloride yield vanadium(IV) complexes. The spectral data reveal that oxovanadium(IV) complexes are square pyramidal while the vanadium(IV) complexes are octahedral.|
