چکیده انگلیسی
μ2-Oxido bridged dinuclear vanadium(V) Schiff base complex with the general formula [VO2(L)]2·2CH3OH was synthesized and characterized. The X-ray results show the complex is dinuclear with two μ-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 μ-O bridges. The other μ-O bridge coordinated to vanadium(V) center as apical direction. The two oxido bridged connected the two Vv centers together with the Vv-O-Vv angle of 101.21(6)°, the VO distances of 1.70(6) and 2.31(7) Ã
and the Vâ¯V separation of 3.113(5) Ã
. Finally, the complex was calcinated at 600 °C for 3 h. The FT-IR spectrum of the product shows the formation of the V2O5 particles.
