| Abstract: | Five complexes WO(NCS)4L–L] (where L–L = benzoic acid1-(Furan-2-yl)methylene]hydrazide(BFMH), benzoic acid(thiophen-2-yl)methylene]hydrazide(BTMH), benzoic acid1-(thiophen-2-yl)ethylidene]hydrazide(BTEH), benzoic acid(phenylmethylene)hydrazide(BPMH) and benzoic acid1-(anisol-3-yl) methylene]hydrazide(BAMH)) have been prepared by reaction of ammonium tetraisothiocyanatodioxotungstate(VI) with the corresponding ligand in aqueous medium in the presence of hydrochloric acid. The complexes have been characterized by elemental analysis, molar conductivity, magnetic moment measurements, IR, electronic spectra, thermogravimetric analysis TGA/DTA and 1H NMR. |
