A new potential tetradentate ligand, N-benzoyl-N′ -p-hydroxythiobenzhydrazine (H2Bptbh) has been found to form complexes [VO(Bptbh)], [Fe(HBptbh)2(acac)] and [M(HBptbh) 2] (M = CuII, ZnII, CdII) by loss one or two proton(s) from the ligand. The complexes have been characterized by elemental analyses, magnetic susceptibility measurement, UV-vis, IR, ESR, 1H NMR, Moessbauer and FAB mass spectral studies. The room temperature ESR spectra of OVIV, FeIII and Cu II complexes yield 〈g〉 values characteristic of square pyramidal, octahedral and square planar complexes, respectively. The Moessbauer spectra of [Fe(HBptbh)2(acac)] at room temperature and 78 K suggest the presence of high spin FeIII. The solid state conductivity of [VO(Bptbh)], [Fe(HBptbh)2(acac)] and [Cd(HBptbh) 2], increase in temperature range 323-333 K with a band gap of 0.42-0.75 eV, indicating their semiconducting behaviour. Other complexes are insulators.
