摘要
利用硝酸铋和哌啶氨荒酸盐反应,合成了一维链状铋配合物[Bi(S2CNC5H10)2?(NO3)]∞。通过元素分析和红外光谱对其结构进行了表征。用X-射线单晶衍射测定了该配合物的晶体结构,测试结果表明:配合物晶体属单斜晶系,空间群P21/c,a=13.802(3),b=6.2005(13),c=22.587(5)?,β=103.509(3)o,V=1879.5(7)?3,Mr=591.53,Z=4,F(000)=1136,Dc=2.090g/cm3,μ(MoKα)=9.840mm–1,R=0.0301,wR=0.0399。在该配合物中,铋原子为六配位的畸变八面体构型。通过硝酸根的桥连作用,形成了一维链状结构。
YIN Han-Dong WANG Chuan-Hua WANG Lei (Department of Chemistry, Liaocheng University, Liaocheng 252059, China) The one-dimensional chain bismuth complex [Bi(S2CNC5H10)2?(NO3)]∞ was synthesized, and its crys- tal and molecular structures were determined by X-ray single-crystal diffraction. The crystal belongs to monoclinic, space group P21/c with a = 13.802(3), b = 6.2005(13), c = 22.587(5) ?, β = 103.509(3)o, V = 1879.5(7) ?3, Z = 4, F(000) = 1096, Dc = 2.090 g/cm3, μ(MoKα) = 9.840 mm–1, R = 0.0301 and wR = 0.0399. The structure shows a six-coordinated distorted octahedral configuration for the central Bi atom and the bridging nitrate groups link the Bi atoms to form a one-dimensional chain polymer.
