| 摘要: 以4-甲氧基水杨醛和季戊四胺进行缩合反应得到席夫碱化合物 H4L,然后将配体H4L分别与Ni(ClO4)2·6H2O、Cu(ClO4)2在乙醇溶液中进行配位反应,得到2个席夫碱配合物[Ni2(L)]·DMF (1)和[Cu4(L)2(DMSO)3]·2DMSO (2).并用元素分析、FT-IR和X射线单晶衍射进行了表征.配合物1和2都属于三斜晶系,P1空间群,配合物1和2都为双核配合物.初步研究了配体和配合物的体外抑菌活性,结果表明,配体及其配合物1和2对金黄色葡萄球菌具有一定的抑菌活性. |

| Abstract: The Schiff base compound H4L was synthesized from condensation reaction of 4-Methoxysalicylaldeh-yde with Pentaerythrityltetramine. H4L was reacted with Ni(ClO4)2·6H2O or Cu(ClO4)2·6H2O to give two complexes [Ni2(L)]·DMF (1) and [Cu4(L)2(DMSO)3]·2DMSO (2). The complexes were characterized by elemental analysis, FT-IR and single crystal X-ray diffraction. The crystals of 1 and 2 belong to the triclinic system, space group P1. The complexes 1 and 2 are all binuclear complexes. The In vitro bacteriostatic activities of the ligand and complexes were tested against several kinds of bacteria. The results show that the ligand and complexes possess different bacteriostatic activities to S. aureus. CCDC: 1436577, H4L; 1436578, 1; 1436576, 2. |
