摘要：

A new polyoxovanadate compound[Co(pIM)V2O6](1)was hydrothermally synthesized,where pIM standsfor2-(2-pyridyl)imidazole.For its characterizations,an integration of X-ray single crystal diffraction,powder X-raydiffraction,Fourier transform infrared spectra,and elemental analysis was accomplished.The compound exhibited a2D architecture composed of VO(4)tetrahedra and CoO(3)N(2)square pyramids via both edge- and corner-sharing.Considering the excellent catalytic oxidation features of polyoxovanadate,compound1was used as an efficientheterogeneous catalyst for the epoxidation of olefins with H(2)O(2)as an oxidant,and could be reused without consum-ing activity.Besides,the magnetic studies indicated the antiferromagnetic interactions in1.CCDC:2285966.
