【Abstract】 A novel 2D supramolecular complex ·(C9H11N3OS) was synthesized by the reaction of 2-hydroxyacetophenone thiosemicarbazone,vanadyl acetylacetonate,sodium acetate,in a mixed of methanol and water.The crystal structure of title compound was reported by X-ray diffraction.The crystal is of triclinic,space group P1-with unit cell parameters:a=0.780 87(9)nm,b=1.232 82(13)nm,c=1.337 4(2)nm,α=108.708(8)°,β=91.299(8)°,γ=107.652(6)°,V=1.151 7(3) nm3,Z=2,Dc=1.420 g·cm-3,μ=0.565 mm-1,F(000)=514,R1=0.0516,ωR2=1.1022.The coordination geometry of the V(Ⅳ) atom was a ideal octahedral configuration.The complex are assembled by hydrogen bonds and π-π interactions into a 2D layer supramolecular structure.The luminescent and TGA properties of the complex have been further studied and discussed.CCDC:764394.更多还原
