【Abstract】 A novel heteropoly tungstomolybdophosphate,[CH3NH3][NH3(CH2)6NH3]H3[P2Mo2W16O62] ·H2O has been synthesized and characterized by elemental analysis, IR, TGA-DSC and single-crystal X-ray structure analysis. Crystal data; monoclinic, space group P21/m, a = 1.259 6(3) nm, b = 1.871 5(4) nm, c=l. 981 6(4) nm, a=γ=90°, β=90. 16(3)° V = 4. 671(2) nm3, Z=2, Mr = 4 358. 66, Dc = 3. 100 g cm-3, μ=19. 978 mm-1, F(000) = 3 792, R = 0. 083 5, Rw = 0. 202 6. The structure analysis shows that a kind of micropore with size of 0. 736 4 nm×0. 835 4 nm was formed in the crystal structure.更多还原
