چکیده مقاله :
In present studies the synthesis, characterization and biological properties ofoxovanadium(IV) coordination compounds of 4[N-(4′-ethylbenzalidene)amino] antipyrinethiosemicarbazone (EBAAPTS) and 4[N-(2′,4′-dimethylbenzalidene)amino] antipyrinethiosemicarbazone (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 thecomplexes were characterized by elemental analyses, molar mass, molar conductance, magneticsusceptibility, infrared and electronic spectra. In all these complexes, both thethiosemicarbazones behave as neutral tridentate (N, N, S) ligands. The thermal properties of therepresentative complexes are also reported. The most probable geometry of the complexes isproposed.
