用5-甲基水杨醛、4-二乙氨基水杨醛分别与卡巴肼或硫代卡巴肼缩合,制得1,5-二取代卡巴肼或硫代卡巴肼配体。在微波甲醇溶剂热条件下,二苄基二氯化锡前体与配体反应,合成了双(取代水杨醛)缩(硫代)卡巴肼苄基锡配合物T1~T4,但T4的结构与T1~T3不同,T4由N,N′-双(4-二乙氨基水杨醛)缩连氮及甲氧基桥联锡组成的苄基锡配合物,T4还可由卡巴肼、4-二乙氨基水杨醛和二苄基二氯化锡“一锅法”合成。T1~T4的结构经元素分析、IR、~1H/~(13)C NMR表征,并用X射线衍射法确证配合物T4的晶体分子结构。T4属单斜晶系,P2_1/c空间群,中心锡原子与氮、氧、苄基碳和氯原子组成六配位变形八面体构型。T4在DMF-H_2O溶液中...

The 1,5-disubstituted carbohydrazide and thiocarbohydrazide ligands were prepared by condensation of carbohydrazide, thiocarbohydrazide with 5-methylsalicylaldehyde, 4-diethylaminosalicylaldehyde, respectively. Their benzyltin complexes, T1 similar to T4 were obtained by microwave-assisted solvothermal reaction of dibenzyltindichloride precursor with the ligands in methanol environments. However, the structure of T4 is different from those of T1 similar to T3, which is a benzyltin complex bridged by N,N'-bis(4-diethylaminosalicylaldehyde) azine and methoxy group. Also, T4 can be synthesized by...
