卡巴肼分别与水杨醛和香草醛缩合制备1,5-不对称二取代卡巴肼配体,在甲醇溶剂热中,正丁基三氯化锡与配体反应,合成1-(水杨醛)-5-(香草醛)缩卡巴肼丁基锡配合物(B1)和含N,N′-双水杨醛缩连氮分子的丁基锡配合物(B2),经元素分析,IR, ~1H、~(119)Sn、~(13)C NMR和X射线衍射晶体结构表征,配合物(B1)、(B2)晶体分别属单斜晶系、P2_1/n空间群和三斜晶系、P1空间群,中心锡与配基原子构成六配位畸形八面体构型,配合物(B1)在DMF-H_2O溶剂体系中具有良好的荧光性质,当含水0~10%(V/V)时具有聚集荧光增强效应,含水量大于10%,随含水体积分数增加荧光强度减弱,以至最后淬灭。配体及其配合物(B1)对马齿苋、刺苋...

The 1,5-asymmetric disubstituted carbohydrazide ligands were prepared by condensation of carbohydrazide with salicylaldehyde and then with vanillin. The butyltin complex Bl based on the 1,5-disubstituted carbohydrazide and the complex B2 containing salicylaldehyde azine were obtained by solvothermal reaction of n-BuSnCl3 with the ligand in methanol environments, which have been structurally characterized by elemental analysis, IR and1H,13C,119Sn NMR spectra. The crystal of complex B1 belongs to monoclinic system, space group P21/n, and the crys...
