An organic-inorganic hybrid complex, [H2(PW12O40){Zn(C10H8N2)2(H2O)}]·1.5[Zn(C10H8N2)3]·1.75H2O has been synthesized hydrothermally and structurally characterized by X-ray crystallography. The crystal belongs to monoclinic, space grounp C2/c, with a=4.709 4(2) nm, b=1.431 77(7) nm, c=2.621 07(1) nm, β=90.125(4)°, V=17.673 4(2) nm3, Z=8, Dc=3.087 Mg·m-3, F(000)=14 884, μ(Mo Kα)=16.327 mm-1. The structure was refined to R1=0.068 7 and wR2=0.158 0 for 20 128 observed reflections with I>2σ(I). Single crystal structure shows that the title compound is constructed from [PW12O40]3- cluster anion and [Zn(C10H8N2)2(H2O)]2+ metal-organic complex cation, in which metal Zn(Ⅱ) cation are coordinately bonded to the terminal oxygen of Keggin polyanions. The title compound exhibits good catalytic activity for oxidation of benzaldehyde to benzoic acid. CCDC: 624772. 相似文献
