Sažetak
Transition-metal complexes of thiosemicarbazones are of great interest because of their chemical and pharmacological properties [1]. In a continuation of our studies on the chelating behaviour of thiosemicarbazones (such as ONS ligands) on molybdenum [2] and vanadium, we have prepared several new vanadium(V) complexes of the general formula [VO{; ; XC6H3(O)CHNNHC(S)NHC6H5}; ; (RO)] [X = H or OCH3 ; R = CH3, C2H5, C3H7, C4H9. The complexes have been characterized by chemical and thermogravimetric analysis, X-ray powder diffraction, IR and in some cases, single crystal X-ray diffraction method. The complexes of vanadium(V) are in a tetragonal-pyramidal environment coordinated by oxo- oxygen of vanadyl moiety in the apical position, RO and tridentate thiosemicarbazone ligand in the plane.
