Synthesis and Characterization of Molybdeum(V) Complexes

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.
