| 摘 要： | A new complex bis(N-salicylidene-N′-aminoethanol)dioxovandium(Ⅴ)], V(Ⅴ)O2(SALAE)]2, was synthesized by the reaction of salicylaldehyde and aminoethanol with vanadyl sulfate. It was characterized by elemental analysis, IR and X-ray single crystal diffraction analysis. The crystal of the title complex (C18H20N2O8V2, Mr = 494.24) belongs to monoclinic, space group P21/c with the following crystallographic parameters: a= 1.7966(6) nm, b= 0.7587(3) nm, c= 2.1539(7) nm, β = 92.551 (6) °, V= 2.9329 (17) nm3, Z= 6, Dc= 1.679 g·cm-3, μ(MoKα) = 1.006 mm-1, F(000) =1512, and final R1 = 0.0563, wR2= 0.1243 for observed reflections 2861(I> 2σ(I)). The complex is a bis(μ-oxo)-bridged V(Ⅴ) schiff base dimer formed by two dioxovandium units, V(Ⅴ) is six-coordinated and forms a distorted octahedral structure. The thermal decomposition for the complex was studied by TG-DTG curves and the apparent activation energy was obtained by the Kissinger formula. CCDC: 211147.

The complex is a bis(μ-oxo)-bridged V(Ⅴ) schiff base dimer formed by two dioxovandium units, V(Ⅴ) is six-coordinated and forms a distorted octahedral structure. The thermal decomposition for the complex was studied by TG-DTG curves and the apparent activation energy was obtained by the Kissinger formula. CCDC: 211147. |
