|Abstract:||The flexibly-bridged hexadentate tetraanionic ligands, L4- [LH4 = schiff base derived from the condensation of methylene- or dithiobis(salicylaldehyde) with benzoylhydrazide or p-nitrobenzoylhydrazide] and their binuclear dioxomolybdenum(VI) complexes have been synthesized and characterized by elemental analyses, molar conductance, IR, NMR and electrometric studies. The isolated complexes have an oligomeric structure, [(MoO2)2L]n in which each molybdenum achieves a pseduo-octahedral structure via MoO -> Mo bridging. The complexes accept neutral donor molecules (D) like pyridine, 4-methylpyridine, imidazole, etc., through their sixth labile binding site available in both [MoO2]2+ units and form [(MoO2)2L(D)2]. The cyclic voltammetric measurements indicate irreversible to quasireversible reduction of the molybdenum(VI) complexes to molybdenum(lV) with a cathodic reduction potential of - 0.83 to - 0.85 V vs SCE at the scan rate of 200 mV/ s.|
