Abstract

In present studies the synthesis, characterization and biological properties of
oxovanadium(IV) coordination compounds of 4[N-(4′-ethylbenzalidene)amino] antipyrine
thiosemicarbazone (EBAAPTS) and 4[N-(2′,4′-dimethylbenzalidene)amino] antipyrine
thiosemicarbazone (DMBAAPTS) with the general composition VOX2L (X = C1-, Br-, I-, NO3
-
or NCS-) and VO(CIO4)2(L)H2O (L = EBAAPTS or DMBAAPTS) are described . All the
complexes were characterized by elemental analyses, molar mass, molar conductance, magnetic
susceptibility, infrared and electronic spectra. In all these complexes, both the
thiosemicarbazones behave as neutral tridentate (N, N, S) ligands. The thermal properties of the
representative complexes are also reported. The most probable geometry of the complexes is
proposed.
