摘要
利用4-巯基苯甲酸(4-H2SBA),乙醇钠与三烃基锡在1:1:1的摩尔比下反应,合成了四个4-巯基苯甲酸的三烃基锡(VI)衍生物:R3Sn[S(C6H4CO2H)](R=CH3-1;n-Bu-2;Ph-3;PhCH2-4),与二烃基锡在1:2:2的摩尔比下合成了两个4-巯基苯甲酸的二烃基锡(VI)衍生物R2Sn[p-S(C6H4CO2H)]2(R=n-Bu-5;Ph-6)。并通过元素分析,红外光谱,核磁共振氢谱对其结构进行了表征。研究表明配合物1-6都是通过4-巯基苯甲酸上S原子而不是羧基上的O原子与锡配位。这一配位特征也被配合物3和5的X-射线单晶衍射结构所证明。此外,晶体结构分析还表明,配合物3是一个通过分子间O-H...O氢键作用形成的二聚体。
The reaction of triorganotin（IV） chloride, 4-sulfanylbenzoic acid and EtONa in the molar ration of 1 ： 1 ： 1 obtained four new complexes with the type： R3Sn[SLL6H4CO2H] （R = CH3 1 ; n - Bu 2; Ph 3; PhCH2 - 4） and the reaction of diorganotin（IV） dichloride, 4-sulfanylbenzoic acid and EtONa in the molar ration of 1：2：2 obtained two new complexes with the type： R2Sn[ p - SLL6H4CO2H） ]2 （ R = n - Bu 5 ; Ph 6）. All complexes 1 - 6 were characterized by elemental analyses, IR, 1H NMR spectra. It has been shown that the coordination behaviour of 4-sulfanylbenzoic acid is monodentate in 1 -6 by thiol S atom but not carboxylic oxygen atom. Among them, the structure of complex 3 and 5 were also determined by X-ray diffraction. Besides, it has been shown that complex 3 is a dimer connected by intermolecular double O - H... O hydrogen bonding interactions.
