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 with the following crystallographic parameters:a=1.543 5(5) nm,b=0.6620(2)nm,c=1.648 9(6) nm,β=105.043(7)°,V=1.627 3(10) nm3,Z=4,Dc=1.528g.cm-3,μ(MoKa)=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.
