摘要
首次报道了新型高聚合度钨磷多金属氧酸盐超分子化合物H16{[P4W14Na3 (H2O)7O58]2[Na4(H2O)13]2[P4W14Na2(H2O)2O56]}·24H2O的水热合成方法,用元素分析、IR和单晶X射线衍射等手段进行了表征.晶体属三斜晶系,P1空间群,a= 1.551 5(3)nm,b=1.866 4(4)an],c=2.224 9nm,α=105.10(3)°,β=96.74(3)°,γ= 95.23(3)°,V=6.127(2)nm3,Z=1,Mr=12 418.36,Dc=3.365 g·cm-3,μ=19.843 mm-1, F(000)=5 516,R=0.0 829,Rw=0.2 020.测定结果表明,标题化合物是由两个[P4W14Na3 (H2O)7O58]9-和一个[P4W14Na2(H2O)2O56]6-阴离子通过O-Na-O桥键合而成.
A novel high poly tungstophosphate supramolecular compound, H16 { P4 W14 Na3 (H2 O) 7 O58 } 2 [Na4 (H2 O)13 ]2 [P4 W14 Na2 (H2 O)2 O56 ] }·24H2 O has been firstly synthesized by hydrothermal method and characterized by elemental analysis, IR and single-crystal X-ray structure analysis. The crystal is triclinic system with space group pl,a=1. 551 5(3) nm, b=1. 866 4(4) nm,c=2. 224 9 nm,a= 105. 10(3)°,β=96. 74(3)°,γ=95. 23(3)°,V=6. 172(2) nm^3,Z= 1,Mr=12 418. 36,Dc=3. 365 g·cm^-3 ,μ=19. 843 mm^-1] ,F(000)=5 516,R=0. 082 9,Rw=0. 202 0. The result of structure analysis shows that the title compound consists of two [P4 W14Na3 (H2O)7 O58 ]^9-and [P4W14 Na3 ( H2O)7 O56 ]^6- anion and linked O-Na-O.
