在苯溶液中,将2-(2-甲酰基-6-甲氧基苯氧基)乙酸与二正丁基氧化锡进行脱水反应,获得新型二正丁基锡(Ⅳ)羧酸酯(1),经过元素分析、1HNMR和IR及晶体结构测定等手段对其进行了结构表征。锡原子为五配位,构成以锡为中心的扭曲三角双锥构型,三个双锡氧环构成具有对称结构的二聚体。中心环[Sn2O2]通过氧原子与两个环外锡原子相连,双齿配体羧基的两个氧原子分别与环内和环外锡原子配位,每个环外锡原子还与羧基形成单齿配位。此外还初步研究了其杀菌活性。
In the benzene solution, 2- (2-formyl-6-methoxyphenoxy) acetic acid is dehydrated with di-n-butyltin oxide to obtain novel di-n-butyltin (Ⅳ) carboxylate After elemental analysis, 1HNMR and IR crystal structure determination and other means of their structural characterization. The tin atom is five-coordinated, forming a twisted triangular bipyramid configuration centered around tin, and three double tinoxides form a dimer with a symmetrical structure. The central ring [Sn2O2] is linked to two exocyclic tin atoms via oxygen atoms. The two oxygen atoms of the carboxyl group of the bidentate ligand are coordinated with the exocyclic and exocyclic tin atoms, respectively, and each of the exocyclic tin atoms forms a mono Tooth coordination. In addition, preliminary study of its bactericidal activity.
