摘　　要：利用二丁基氧化锡与2,6-吡啶二甲酸反应合成了目标化合物{n-Bu2Sn[2,6-(O2C)2C5H3N](H2O)}2。用元素分析、红外光谱、核磁共振氢谱以及X-射线单晶衍射进行了表征和结构测定。X-射线单晶衍射测定表明,该化合物为四方晶系,空间群P4(2)/n,a=1.7721(5)nm,b=1.7721(5)nm,c=1.1164(4)nm,α=β=γ=90,°Z=4,V=3.5060nm3,F(000)=1680,R1=0.0344,wR2=0.0853。化合物中两个锡原子呈七配位畸变五角双锥构型。The organotin compound {n-Bu2Sn[2,6-（O2C）2C5H3N]（H2O）}2 was synthesized by the reaction of 2,6-pyridine dicarboxylic acid with n-Bu2SnO and characterized by elemental analysis, IR and ^1HNMR spectra. The crystal and molecular structures were determined by X-ray single crystal diffraction. The crystal of compound belongs to tetragonal with space group P4（2）/n, a = 1.7721 （5）nm, b = 1.7721 （5）nm, c = 1.1164 （4）nm, α = β = γ = 90°, Z = 4, V = 3.5060nm^3, F（000） = 1680, R1 = 0.0344, wR2 = 0.0853. In compound, two central tin atoms adopted distorted pentagonal bipyramidal structure.
