摘要/Abstract

摘要： 三氯乙酸与氧化双[三(2-甲基-2-苯基)丙基锡]反应，合成了新配合物三(2-甲基-2-苯基)丙基锡三氯乙酸酯（CCDC:932139），经元素分析、1H NMR和IR等技术手段表征其组成和结构，通过X射线衍射方法测定了化合物的晶体结构。该化合物晶体学参数：单斜晶系，空间群为P21/n，晶胞参数：a=1.1186(4) nm，b=1.8366(7) nm，c=1.6020(6) nm，α=90°，β=91.316(7)°，γ=90°，V=3.2902(19) nm3，Z=4，Dc=1.374 g/cm3，μ(MoKα)=1.046 mm-1，F(000)=1392，R1=0.0589，wR2=0.1619；中心锡原子呈四配位畸变四面体构型。生物活性测试结果表明，标题配合物对5种肿瘤细胞株系HT-29、HepG-2、MCF-7、KB和A549均具有较好的体外抑制活性，并且具有选择性的抑菌活性。

Abstract: The title complex, tris(2-methyl-2-phenyl) propyl tin trichloroacetic acid ester(CCDC:932139), was synthesized by the reaction of bis[tris(2-methyl-2-phenyl)propyl]tin oxide with trichloroacetic acid and characterized by IR, 1H NMR spectroscopy and elemental analysis, respectively. The crystal structure was determined by X-ray diffraction to be monoclinic with a P21/n space group with a=1.1186(4) nm, b=1.8366(7) nm, c=1.6020(6) nm, α=90°, β=91.316(10)°, γ=90°, V=3.2902(19) nm3, Z=4, Dc=1.374 g/cm3, μ(MoKα)=1.046 mm-1, F(000)=1392, and R1=0.0589, wR2=0.1619. The crystal structure shows that the central Sn atom is four-coordinated to assume a distorted tetrahedral configuration. Bioassay results show that the complex displays good in vitro antitumor activities against five human tumor cell lines, HT-29, HepG-2, MCF-7, KB and A549, and has selective antibacterial property.
