用1,4-环己二酸分别与三苯基氯化锡,三甲基氯化锡,三丁基氯化锡,三苄基氯化锡反应,得到了[(Ph3Sn)2](C8H10)(COO)2]1,(Me3Sn)2[(C8H10)(COO)2]2,[(n-Bu)3Sn]2[(C8H10)(COO)2]3和[(PhCH2)3Sn]2[(C8H10)(COO)2]4四个新型的化合物,并通过元素分析、红外光谱和核磁共振氢谱对其结构进行了表征.其中化合物1还通过X-射线单晶衍射进行了表征.单晶结构表明配合物1是一个二锡核的单体三苯基锡化合物,在配合物1中羧酸配体上的两个羧基都参与了配位,中心锡原子都是扭曲的四配位的四面体构型.
Reaction of 1,4-cyclohexanedioic acid with triphenyltin chloride, trimethyltin chloride, tributyltin chloride and tribenzyltin chloride gave [(Ph3Sn) 2] (C8H10 (COO) 2] 1, (Me3Sn) 2 [(C8H10) (COO) 2] 2, [(n-Bu) 3Sn] 2 [(C8H10) (COO) 2] 3 and [(PhCH2) 3Sn] 2 [(C8H10) (COO) 2] 4, and its structure was characterized by elemental analysis, IR and 1H-NMR. Compound 1 was also characterized by X-ray single crystal diffraction. The single-crystal structure indicates that the complex 1 is a monomeric triphenyltin compound of di-tin nuclei. The two carboxyl groups on the carboxylic acid ligands in the complex 1 all participate in the coordination. The central tin atoms are all distorted with four Bit tetrahedral configuration.
