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。

关键词: 混合二烃基二氯化锡, Schiff碱配合物, 合成

Abstract: 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-DSCand XRDstudies indicate the ligands coordinate to Sn atom via phenolic Oatom rather than imide Natom, under different reaction conditions, the same organotin compound and the same Schiff base can form the complex to have different coordination number.
