摘要: 用5-氯邻羟苯甲醛与2-氨基-5-硝基噻唑(L1H)和4-氯苯甲醛与2-氨基-3-羟基吡啶(L2H)的反应,再用传统和微波方法将生成物与Cr(Ⅲ),Co(II),Ni(Ⅱ)和Cu(Ⅱ)合成了一些席夫碱配合物。用元素分析,FTIR,快原子轰击质谱,摩尔电导率,电子光谱,1H-NMR,ESR,磁化率,热分析,电导率和XRD等对这些化合物进行了表征。这些配合物在空气中稳定并有颜色。分析数据表明所有配合物金属与配体的比均为1∶2,配位数为4或6。原子轰击质谱和热分析数据说明了这些配合物的降解方式。XRD图给出了这些配合物的结晶情况。席夫碱的上述金属配合物对革兰氏阳性菌:金黄色葡萄球菌和革兰氏阴性菌:大肠埃希菌(大肠杆菌)和真菌:黑曲霉和白色念珠菌显示出良好的抗菌活性。

Abstract: Some new Schiff base complexes of Cr(Ⅲ), Co(Ⅱ), Ni(Ⅱ) and Cu(Ⅱ) derived from 5-chlorosalicylaldehyde with 2-amino-5-nitrothiazole (L1H) and 4-chlorobenzaldehyde with 2-amino-3-hydroxypyridine (L2H) have been synthesized by conventional as well as microwave methods. These compounds have been characterized by elemental analysis, FTIR, FAB-mass, molar conductance, electronic spectra, 1H-NMR, ESR, magnetic susceptibility, thermal, electrical conductivity and XRD analysis. The complexes are coloured and stable in air. Analytical data reveal that all the complexes exhibit 1∶2 (metal∶ligand) ratio with coordination number of 4 or 6. FAB-mass and thermal data show degradation pattern of the complexes. XRD patterns indicate crystalline nature for the complexes. The Schiff base and metal complexes show a good activity against the Gram-positive bacteria: Staphylococcus aureus and Gram-negative bacteria: Escherichia coli and fungi: Aspergillus niger and Candida albicans.
