The Mo(V) $di-{\mu}-oxo$ type $[Mo_2O_4(H_2O)_2L]Cl_2$ complexes(L: 4,4'-Diphenyl-2,2'-dipyridyl, 4,4'-Dimethyl-2,2'-dipyridyl, 4,7-Diphenyl-1,10-phenanthroline) have been prepared by the reaction of $[Mo_2O_4(H_2O)_6]^{2+}$ 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 $Mo_2O_4(H_2O)_2L$ two $H_2O$ coordinated at trans site of terminal oxgens. The prepared complexes have been characterized by elemental analysis, infrared spectra, electronic spectra, $^1H$ nuclear magnetic resonance spectra, and thermal analysis(TG-DTA). In the potential range -0.00V to -1.00V at scan rate of $50mVs^{-1}$, a cathodic peak at -0.83V ${\sim}$ -0.88V (vs SCE) and an anodic peak at -0.54V ${\sim}$ -0.88V (vs SCE) have been observed in aquous solution. The ratio of the cathodic to anodic current(Ipc/Ipa) is almost 2, we infer that redox is irreversible as dimer forms broken.

The Mo(V) $di-{\mu}-oxo$ type [$Mo_{2}O_{4}(H_{2}O)_{2}L_{2}$] $SO_{4}$ complexes(L: 2,2'-dipyridyl,4,4'-ethylenedianlline) have been prepared by the reaction of $[Mo_{2}O_{4}(H_{2}O)_{6}]SO_{4}$ 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 $Mo_{2}O_{4}(H_{2}O)_{2}L_{2}$, two $H_{2}O$ coordinated at trans site of terminal oxygens. The prepared complexes have been characterized by elemental analysis, infrared spectra, $^{1}H$ 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 ${\sim}$ -0.87V (vs SCE) and an anodic peak at -0.61V ${\sim}$ -0.63V (vs SCE) have been observed in aquous solution. We infer these redox are irreversible reaction.
