Abstract We report here the straightforward synthesis of some dimeric transition metal complexes of three Schiff base ligands, which were obtained by condensation of 2-tosylaminomethylaniline with 2,3-dihydroxybenzaldehyde (H2L1), 2,4-dihydroxybenzaldehyde (H2L2), and 4-formyl-3-hydroxybenzoic acid (H2L3), respectively. Both ligands and complexes were characterized by a combination of 1H NMR, infrared
摘要 我们在此报告了三个席夫碱配体的一些二聚过渡金属配合物的直接合成,这些配合物是通过 2-甲苯磺酰氨基甲基苯胺与 2,3-二羟基苯甲醛 (H2L1)、2,4-二羟基苯甲醛 (H2L2) 和 4-分别为甲酰基-3-羟基苯甲酸 (H2L3)。配体和配合物均通过 1H NMR、红外和质谱以及元素分析的组合进行表征。此外,通过X射线衍射阐明了H2L2和Pd2L22·2MeOH的晶体结构。Pd2L22·2MeOH 的晶体结构不是典型的μ-Ophenoxo 桥,而是通过不寻常的μ-Nsulfonamido 桥连接在一起的重复单元。这种配合物是手性的,虽然它结晶为外消旋体,具有 C2v 对称性,
