The Mo(V) di-μ-oxo type [Mo2O4(H2O)2L2] SO4 complexes(L: 2,2'-dipyridyl,4,4'-ethylenedianlline) have been prepared by the reaction of [Mo2O4(H2O)6]SO4 with a series of chelate ligands. These complexes are completed by two terminal oxygens arranged trans to one another and each ligand forms a chelate types. In Mo2O4(H2O)2L2, two H2O coordinated at trans site of terminal oxygens. The prepared complexes have been characterized by elemental analysis, infrared spectra, 1H nuclear magnetic resonance spectra, and thermal analysis(TG-DTA). In the potential range -0.00V to -1.00V at a scan rate of 50mVs-1, a cathodic peak at -0.81V ~ -0.87V (vs SCE) and an anodic peak at -0.61V ~ -0.63V (vs SCE) have been observed in aquous solution. We infer these redox are irreversible reaction.
