Abstract A new potential tetradentate ligand, N-nicotinoyl-N′-2-furanthiocarbohydrazide (H2Nfth), and its complexes with VOIV, MnII, FeII,III, CoII, NiII, CuII and ZnII have been prepared and characterized by elemental analyses, magnetic susceptibility measurements, u.v.–vis, i.r., n.m.r., ES+ and FAB mass spectral data. The room temperature e.s.r spectra of the VOIV and FeIII complexes yield 〈g〉 values, characteristic of octahedral complexes. The Mössbauer spectra of [Fe(HNfth)2] and [Fe2(Nfth)3] at room temperature and at 78 K suggest the presence of high-spin iron(II) and iron(III), respectively. The complexes are electrically insulating at room temperature, however, their conductivities increase as the temperature increases from 333–383 K, with a band gap of 0.46–0.77 eV, indicating their semiconducting behaviour. H2Nfth and its soluble complexes have been screened against several bacteria and fungi.
