摘要:The complex tributy ltin 4-pyridinecarboxylate was synthesized by reaction of tributyltin chloride with sodium 4-pyridinecarboxylate in benzene. It has been characterized by IR,1H NMR,elemental analyses,MS and Xray structural analyses. The crystals are monoclinic, space group p21/c, with a = 9. 667 3 (14), b = 23. 845 (4), c =9. 707 1 (14) A,β=112. 463 (3);V=2 067.9(5)A3,Z=4,Dc=1. 324 Mg m-3,μ= 1.242 mm-1,F(000)=848,R1 = 0.054 4,wR2 = 0.141 1. In the crystals the tin atoms are rendered five-coordinate in a trigonal bipyramidal structure by coordinating with 4-pridinylcarboxlate group. The resulting structure is a linear polymer containing Sn-O and Sn-N bonds whose lengths are 2. 170(5) A and 2.60(2) A,respectively.%用三丁基氯化锡与4-吡啶甲酸钠反应,合成了三丁基锡4-吡啶甲酸酯,并进行了红外光谱、核磁共振氢谱及质谱表征.X-射线单晶衍射表明,化合物属单斜晶系,空间群P21/c,a=9.667 3(14),b=23.845(4),c=9.707 1(14)A;β=112.463(3)°;V=2 067.9(5)A,Z=4,Dc=1.324 Mg m-3,μ=1.242 mm-1,F(000)=848,R1=0.054 4,wR2=0.141 1.化合物通过4-吡啶甲酸配体的氮原子桥联,形成五配位三角双锥构型的一维无限链聚合物.
