摘　　要：The complex VO（SALEN）was synthesized by the reaction of vanadyl sulfate and H2salen.The complex was dissolved in CH2Cl2 and green needle crystal was obtained.It was characterized by elemental analysis,IR and X-ray diffraction analysis.The complex (C16H14N2O3V,Mr=333.23)belongs to triclinic with space group of Pī.The cell parameters are a=6.678（4）*!,b=1.4663（8）*!,c=15.094,α=102.27（11）°β=92.700（10）°γ=98.387（10）°,V=1424.2（13）*!3,Z=4,Dc=1.554g·cm-3,F（000）=684,μ=0.710mm-1,R1=0.0710,WR2=0.0783.The VO2+ion is five-coordinated to form distorted square pyramid.The thermal decomposition for the complex was investigated and the apparent activation energy was obtained by the Kissinger formula.The complex VO(SALEN)was synthesized by the reaction of vanadyl sulfate and H_2salen.The complex was dissolved in CH_2Cl_2 and green needle crystal was obtained.It was characterized by elemental analysis,IR and X-ray diffraction analysis.The complex (C_(16)H_(14)N_(2)O_(3)V,Mr=333.23)belongs to triclinic with space group of Pī.The cell parameters are a=6.678(4)*!,b=1.4663(8)*!,c=15.094,α=102.27(11)°β=92.700(10)°γ=98.387(10)°,V=1424.2(13)*!~3,Z=4,D_c=1.554g·cm^(-3),F(000)=684,μ=0.710mm^(-1),R_1=0.0710,WR_2=0.0783.The VO^(2+)ion is five-coordinated to form distorted square pyramid.The thermal decomposition for the complex was investigated and the apparent activation energy was obtained by the Kissinger formula.
