用三丁基氯化锡与戊二羧酸二钠以2:1摩尔比反应,合成了双（三丁基锡）戊二羧酸酯,并用元素分析、红外光谱、核磁共振氢谱及X-射线单晶衍射进行了表征和结构测定。X-射线单晶衍射法测定表明,化合物属单斜晶系,空间群为Cc,晶胞参数:a=13.984（3）,b=16.164（3）,c=16.894（3）A,β=107.457（3）°,V=3642.9（11）A3,Z=4,C29H60O4Sn2,Dc=1.251g/cm3,μ=1.394 mm-1,R=0.0500,wR=0.0874,F（000）=1416。晶体结构中存在2种化学环境不同的三角双锥构型的锡原子,由于配体中2个羧基在不同方向的交联作用,使化合物呈现三维立体骨架结构,并且在骨架结构中存在沿a、b、c轴3个方向伸展的规则的大环直孔道。
Bis (tributyltin) pentanedicarboxylate was synthesized by the reaction of tributyltin chloride and disodium pentamethacrylate in a molar ratio of 2: 1. Elemental analysis, IR, 1HNMR and X-ray diffraction Single crystal diffraction characterization and structure determination. The results of X-ray single crystal diffraction showed that the compound belongs to the monoclinic system with the space group of Cc and unit cell parameters: a = 13.984 (3), b = 16.164 (3), c = 16.894 107.457 (3) °, V = 3642.9 (11) A3, Z = 4, C29H60O4Sn2, Dc = 1.251 g / cm3, μ = 1.394 mm-1, R = 0.0500, wR = 0.0874, F (000) = 1416. In the crystal structure, there are two kinds of tin atoms with triangular double cones in different chemical environments. Due to the cross-linking of two carboxyl groups in different directions in the ligand, the three-dimensional stereostructure of the compound appears in the crystal structure, , B, c axis 3 directions to extend the rules of the large straight channel.
