合成了从S-苄基二硫代肼基甲酸衍生的Schiff碱的配合物,进行了组成分析、红外、电子光谱和磁性的测定。结果表明,邻氯苯甲醛Schiff碱(以HL_1表示)形成反磁性的八面体配合物,其中配体为单价双齿阴离子。亚苄基丙酮Schiff碱(以HL_2表示)形成钴的双聚结构的配合物[Co_2(HL_2)2(L_2)_2X_2],其中X=Ac~-或Cl~-,并作为桥配体,Co(Ⅱ)有八面体配位环境。配合物具有异常低的磁矩,表明2个Co(Ⅱ)离子之间存在着磁交换相互作用,显反铁磁性。抑菌活性试验表明配体HL_1及其配合物存在活性。
The complexes of Schiff base derived from S-benzyldithiocarbazinic acid were synthesized, and the composition, IR, electronic spectra and magnetic properties were determined. The results show that ortho-chlorobenzaldehyde Schiff base (represented by HL_1) forms a diamagnetic octahedral complex with monovalent bidentate anion. Benzyl acetone Schiff base (represented by HL_2) forms a cobalt complex [Co_2 (HL_2) 2 (L_2) _2X_2], where X = Ac ~ - or Cl ~ (Ⅱ) octahedral coordination environment. The complexes have unusually low magnetic moments, indicating that there is a magnetic exchange interaction between the two Co (II) ions and an antiferromagnetic effect. Antibacterial activity test showed that the ligand HL_1 and its complexes exist activity.
