氧化双[三(2-甲基-2-苯基)丙基]锡分别与庚二酸和辛二酸反应,合成了2个双[三(2-甲基-2-苯基)丙基锡]二元酸酯(CH2)n[CO2Sn(CH2CMe2Ph)3]2[(n=5(1),6(2)],经IR、1H和13C NMR、元素分析和X射线单晶衍射对化合物进行了表征。化合物属单斜晶系,空间群为P21/c。锡原子均为畸型四面体构型,化合物1以氢键作用形成一维链状结构,化合物2以氢键和C-H…π作用形成二维网状结构。化合物1和2在340℃以下具有良好的热稳定性,对人癌细胞Colo205、HepG2、MCF-7、Hela、NCI-H460均具有较好的体外抑制活性,且具有一定的抑菌活性。

The two bis[tri（2-methyl-2-phenyl）propyltin]dicarboxylates （CH2）n[CO2Sn（CH2CMe2Ph）3]2 （n=5 （1）, 6 （2）） have been synthesized by the reaction of pimelic acid and suberic acid with bis[tri（2-methyl-2-phenyl）propyltin] oxide, respectively. IR, 1H and 13C NMR, elemental analysis and X-ray diffraction for the title complexes were presented. The two complexes belong to monoclinic, space group P21/c. The tin atoms have a distorted tetrahedral geometry. A 1D chain structure of complex 1 is generated by intermolecular hydrogen bonds and a 2D network structure of complex 2 is formed by C-H…… O and C-H…… 7r interactions. The thermal gravimetric analysis has showed that the complexes 1 and 2 are stable below 340 ℃. The two complexes showed strong in vitro anti-tumor activity against five human tumor cell lines, Colo205, HepG2, MCF-7, Hela and NCI-H460, and have antibacterial activity.
