摘要
由混合二烃基二氯化锡与水杨醛缩苯胺类Schiff碱反应,合成了24种新的有机锡配合物。经元素分析、NMR、TG-DSC测定和X射线粉末衍射分析,确定有14种是有机锡与Schiff碱的1:1配合物,10种是1:2配合物。配体是以酚羟基氧原子与锡原子配位,摩尔电导率测定表明这些配合物均为非电解质。
Twenty-four new addition complexes of type R′R″SnCl2·2- HOC6H4 CH=NC6H4Rand R′R″SnCl2·(2-HOC6H4CH=NC6H4R)2 have been synthesized by the reactions of mixed diorganotin dichlorides,R′R″SnCl2 (where R′= Et,Bu,Bz;R″=Ph;R′= Et, R″= Bu),with N-arylsalicylideneimines,2- HOC6H4CH=NC6 H4 R(where R= H,4- CH3, 4- OCH3,3-CH3,4-OH).The complexes are non electrolyte in nitrobenzene.NMR (1 H, 13C),TG-DSC and XRD studies indicate the ligands coordinate to Sn atom via phenolic O atom rather than imide N atom, under different reaction conditions,the same organotin compound and the same Schiff base can form the complex to have different coordination number.
