Synthesis, characterization and electrical conductivities of the complexes of oxovanadium(IV), iron(III), copper(II), zinc(II) and cadmium(II) with N-isonicotinoyl-N′-p-hydroxythiobenzhydrazine

A new potential tetradentate ligand, N-isonicotinoyl-N′-phydroxy thiobenzhydrazine (H2INptbh) has been found to form complexes [M(INptbh)] (M = OVIV, CuII, ZnII), [Fe(INptbh)(acac)] by loss of two protons from the ligand whereas, [Cd(HINptbh)2] is formed by loss of one proton. The complexes have been characterized by elemental analyses, magnetic susceptibility measurements UV-Vis, IR, ESR, 1H and 13C NMR, Moessbauer and FAB mass spectral data. The room temperature ESR spectra of OVIV, Fe III and CuII complexes yield 〈g〉 values characteristic of square pyramidal, octahedral and square planar complexes, respectively. The Moessbauer spectra of [Fe(INptbh)(acac)] at room temperature and 78 K suggest the presence of high spin FeIII. The solid state electrical conductivity of the complexes are found to be low with σπ in the range of 10-1-10-9 S cm -1, however the conductivities of [Fe(INptbh)(acac)], [Cu(INptbh)], [Zn(INptbh)] and [Cd(HINptbh)2] increase as the temperature increases from 307-397 K, with a band gap of 0.12 - 0.95 eV indicating their semiconducting behaviour. Other complexes are insulators.
