摘要
合成了具有Keggin结构的钼磷多酸吡啶化合物 (Hpy) 2 (CH3 CN) [HPMo12 O40 ] ,其中py =C5H5N ,并经元素分析、热重分析、IR和X -ray晶体衍射确定了单晶结构 ,其晶体属单斜晶系 ,空间群P2 (1) /n ,晶胞参数为 :a =10 .8879(2 )A ,b =12 .663 9(6)A ,c =19.2 10 8(4 )A ,α =89.9869(1)° ,β =97.3 42 2 (1)° ,γ =90 .0 717(1)° ,V =2 62 7.119(5 )A3 ,Z =2 ,Mr =2 0 2 4.49,Dc =2 .2 3 2g .cm-3 ,F(0 0 0 ) =163 4,R1=0 .0 90 2 ,wR2 =0 .12 80 .钼磷多酸化合物由 1个CH3 CN ,2个Hpy+ 阳离子和 1个 [HPMo12 O40 ] 2 -多阴离子构成 .
A new compound, (Hpy) 2(CH 3CN)[HPMo 12 O 40 ] was synthesis. The formula was determined by elemental analysis, IR,TGA and single crystal X-ray diffraction. Crystal data: monoclinic, space group P2(1)/n, a = 10.8879(2)A,b = 12.6639(6)A,c = 19.2108(4)A ,α=89.9869(1)°, β=97.3422(1)°,γ=90.0717(1)°,V =2627.119(5)A 3, Z = 2, Mr=2024.49, Dc=2.232g.cm -3 , F(000)=1634, R 1=0.0902, wR 2=0.1280. The title compound contains a heteropolyanion [HPMo 12 O 40 ] 2- , one CH 3CN and two Hpy +(py=C 5H 5N).
