摘    要:A new oxovanadium(Ⅴ) ternary complex, VO(L)(hq) H2L: N-salicylidene-N′-aminoethanol; hq: 8-hydroxy quinoline], was synthesized by the reaction of salicyaldehyde, aminoethanol and 8-hydroxy quinoline with vanadyl sulfate. It was characterized by elemental analysis, IR and X-ray diffraction analysis. The crystal of the title complex (C18H15N2O4V, Mr=374.26) belongs to monoclinic, space group P21/n with the following crystallographic parameters: a=1.5435(5) nm, b=0.662 0(2) nm, c=1.648 9(6) nm, β=105.043(7)°, V=1.627 3(10) nm3, Z=4, Dc=1.528 g·cm-3, μ(Mo)=0.636 mm-1, F(000)=768, and final R1=0.056 8, wR2=0.106 7 for observed reflections 957 (I>2σ(I)). The complex is six-coordinate in distorted octahedral geometry. The thermal decomposition for the complex was studied by TG-DTG curves and the apparent activation energy was obtained by the Kissinger formula. CCDC: 218497.
