trimethyltin(IV) complex 1 and four-coordinate triphenyltin(IV) complex 2. But in di-n-butyltin(IV) complex 3, the ligands coordinate to tin(IV) atoms through bi- and monodentate two different forms. Also through intermolecular Sn···O weak interaction, complex 3 presents a weakly bridged dimmeric structure which will decompose to monomer in solution. The in vitro cytotoxicities of the title complexes determined
三种新型有机锡(IV)配合物,即三甲基锡(IV)[3-甲氧基-2-羟基苯基-N-(3-羧基苯基)亚胺]一水合物羧酸盐,[Me 3 Sn(L)(H 2 O),1],三苯基锡 (IV) [3-甲氧基-2-羟基苯基-N-(3-羧基苯基) 亚胺] 羧酸盐、[Ph 3 Sn(L), 2] 和二正丁基锡 (IV) [3-甲氧基-2 -羟基苯基-N-(3-羧基苯基)亚胺]羧酸盐,([(n-Bu) 2 Sn(L)] 2 O} 2 , 3),[HL = 3-甲氧基-2-羟基苯基-N-( 3-羧基苯基)亚胺席夫碱配体],已通过有机锡(IV)氯化物与源自o的席夫碱羧酸配体 HL 反应合成-香草醛和3-氨基苯甲酸。所有配合物均已使用光谱(IR、1 H、13 C、119 Sn NMR 和 ESI-MS)和单晶 X 射线衍射技术进行了表征。结构分析表明,配体在五配位三甲基锡(IV)络合物1和四配位三苯基锡(IV)络
