Abstract

The paper reports the synthesis of crystalline oxovanadium(IV), VO2+, complexes of thiosemicarbazones, i.e. 4[N-(4'-nitrobenzalidene)amino]antipyrinethiosemicarbazone (4'-NO2BAAPTS) and 4[N-(furan-2'-aldimine)amino]antipyrinethiosemicarbazone (FFAAPTS) with general composition VOX2L (X = Cl, Br, I, NO3 or NCS) and VO(ClO4)2(L)H2O (L = 4'-NO2BAAPTS or FFAAPTS). All the complexes were characterized by elemental analyses, molar mass, molar conductance, magnetic susceptibility, infrared and electronic spectra. In all the 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.
