Abstract:

 

The paper reports the synthesis of crystalline  oxovanadium(IV), VO2+, complexes of thiosemicarbazones, i.e.  4[N-(4'-nitrobenzalidene)amino]antipyrine thiosemicarbazone  (4'-NO2BAAPTS) and 4[N-(furan-2'-aldimine)amino]antipyrine  thiosemicarbazone (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.
