摘要
首次合成了[CH_3NH_3][NH_3(CH_2)_6NH_3]H_3[P_2Mo_2W_(16)O_(62)]·H_2O,通过元素分析、红外光谱和X射线单晶衍射对合成产物进行了表征,并用TGA-DSC研究了化合物的热稳定性.晶体属单斜晶系,P2_1/m空间群,a=1.259 6(3)nm,b=1.871 5(4)nm,c=1.981 6(4)nm,α=γ=90°,β=90.16(3)°,V=4.671(2)nm^3,Z=2,M_r=4 358.66,D_c=3.100 g·cm^(-3),μ=19.978 mm^(-1),F(000)=3 792,R=0.083 5,R_w=0.202 6.结果表明,在晶体结构内形成了0.736 4 nm×0.835 4 nm的微孔。
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.
