由2-(1,2-亚乙二硫)亚甲基-3-羰基-5-芳基-4-戊烯酸与三苯基氢氧化锡反应,合成了九个标题化合物3。用X射线衍射法测定了3b的晶体结构。该晶体属三斜晶系,空间群P1,a=0.9074(2)nm,b=1.6809(3)nm,c=2.1834(4)nm,α=77.57(3)ⅲ,β=88.04(3)ⅲ,γ=89.47(3)ⅲ,V=3.2503nm^3,Z=2;R=0.0592。由锡氧原子间距离可推测,该晶体中羧酸根作为双齿配体与锡原子形成了分子内五配位结构。

Nine triphenyltin-2-(1, 2-ethylenedithio) methylene-3-oxo-5-aryl-4- pentenicates were synthesized. The crystal structure of the title compound 3b(C~3~3H~2~8O~3S~2Sn) was determined by X-ray diffraction analysis. The crystal belongs to triclinic system, space group P1 with a=0.9074(2)nm, b=1.6809(3)nm, c=2.1834(4)nm, α=77.57(3)ⅲ, β =88.04(3)ⅲ, γ=89.47(3)ⅲ, V=3.2503nm^3, Z=2; R=0.0592. In crystal of 3b, there exist intramolecular O-Sn coordination bonds, with carboxylate group acting as a bidentate ligand: Sn(1)-O(1)=0.2086(5) and Sn(1)-O(2)=0.2594nm, having a deformed trigonal bipyramidal geometry.
