摘　　要：用4,4' 联吡啶分别与高氯酸银、磷酸二氢银反应,得到了化合物[Ag(4,4' bipyri dine)]ClO41和[Ag(4,4' bipyridine)]H2PO4·2H2O2,通过单晶X射线衍射对它们的结构进行了确证.数据为:1三斜晶系,P 1空间群,Mr=363.50,a=8.181(8),b=8.747(4),c=8.921(7) ,α=80.35(1),β=74.64(1),β=73.48(1)o,V=587.2(8) 3,Z=2,F(000)=356,Dc=2.056g·cm-3,μ=1.951mm-1,R1=0.0467,wR2=0.1301;2单斜晶系,P2/c空间群,Mr=397.07,a=8.566(6),b=8.807(7),c=18.729(17) ,β=101.37(1),V=1385.2(19) 3,Z=4,F(000)=792,Dc=1.904g·cm-3,μ=1.596mm-1,R1=0.0714,wR2=0.1834;结构分析表明,二者皆为一维链状结构.分子间通过静电引力、氢键使得化合物构成二维的超分子化合物.Two complexes, \ClO_4 1 and \H_2PO_4·2H_2O 2, were obtained by selfassembly of AgX (X = ClO^-_4, H_2PO^-_4) with 4,4'bipyridine. Data: 1, Triclinic, P1, M_( r ) = 363.50, a = 8.181(8), b = 8.747(4), c = 8.921(7) , α = 80.35(1), β = 74.64(1), β = 73.48(1)~o, V = 587.2(8) ~3, Z = 2, F(000) = 356, D_( c ) = 2.056 g·cm^(-3), μ = 1.951 mm^(-1), R_1=0.0467, wR_2=0.1301; 2, monoclinic, P2/c, M_( r ) = 397.07, a = 8.566(6), b = 8.807(7), c = 18.729(17) , β = 101.37(1), V = 1385.2(19) ~3, Z = 4, F(000) = 792, D_( c ) = 1.904 g·cm^(-3), μ = 1.596 mm^(-1), R_1=0.0714, wR_2 =0.1834; Xray singlecrystal diffraction shows that the compounds have a onedimensional chain structure, and the compounds are formed twodimensional construction by inter- or intramolecular hydrogen bonds and electrtrostatic forces in solid.
