摘　　要：利用三苯基氢氧化锡与4-吡啶甲酸在乙醇溶液中以摩尔比1∶1反应,合成了有机锡化合物[Ph3SnO2CC5H4NH2O]n。通过元素分析、红外光谱、核磁共振氢谱和X-射线单晶衍射对其结构进行了表征。该化合物为正交晶系,空间群P212121,a=1.22176(19),b=1.4971(2),c=2.4313(4)nm,Z=8,V=4.4471(12)nm3,Dc=1.464g/cm3,μ=1.172mm-1,F(000)=1968,R=0.0437,wR=0.0674。该化合物中心锡原子为五配位三角双锥构型,并且通过4-吡啶甲酸配体的氮原子桥联作用形成一维无限链状结构。Tribenzyltin Ester of 4-Pyridinecarboxylic Acid has been synthesized by the reaction of 4-pyridinecarboxylic acid with Ph3SnOH in 1：1 molar fraction and characterized by elemental analysis, IR and 1H NMR. The crystal structure was determined by X-ray single crystal diffraction. The crystal belongs to Orthorhombic, space group P212121, α=1. 22176 （19）, b = 1. 4971 （2）, c= 2. 4313（4）nm,Z=8,V= 4. 4471 （12）nm^3,Dc=1. 464g/cm^3,μ= 1. 172mm^-1, F（000） = 1968,R= 0. 0437, ωR = 0. 0674. In the crystal, the tin atoms are five-coordinated in trigonal bipyramidal structure by bridging pyridine N atoms,resulting in the chain organotin compound.
