mu(2)-Oxido bridged dinuclear vanadium(V) Schiff base complex with the general formula [VO2(L)](2)center dot 2-CH3OH was synthesized and characterized. The X-ray results show the complex is dinuclear with two mu-O bridging ions, and the vanadium centers have an octahedral N2O4 coordination sphere. The tridentate Schiff base ligand L coordinated to vanadium(V) center as a monoanion in the basal plane. The basal plane is completed by one of the mu-O bridges. The other mu-O bridge coordinated to vanadium(V) center as apical direction. The two oxido bridged connected the two V-v centers together with the V-v-O-V-v angle of 101.21(6), the V-O distances of 1.70(6) and 231(7) angstrom and the V...V separation of 3.113(5) angstrom. Finally, the complex was calcinated at 600 degrees C for 3 h. The FT-IR spectrum of the product shows the formation of the V2O5 particles.
