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髥,Co(II),Ni髤和Cu髤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。
Reaction of 5-chloro-o-hydroxybenzaldehyde with 2-amino-5-nitrothiazole (L1H) and 4-chlorobenzaldehyde with 2-amino-3-hydroxypyridine (L2H) followed by conventional and microwave methods will generate Schiff base complexes with Cr 髥, Co (II), Ni 髤 and Cu 髤 were synthesized. These compounds were characterized by elemental analysis, FTIR, fast atom bombardment mass spectrometry, molar conductivity, electron spectroscopy, 1H-NMR, ESR, magnetic susceptibility, thermal analysis, conductivity and XRD. These complexes are stable and colored in the air. The analytical data show that all complexes have a metal to ligand ratio of 1: 2 and a coordination number of 4 or 6. Atomic bombardment mass spectrometry and thermal analysis data illustrate the degradation of these complexes. The XRD pattern shows the crystallization of these complexes. Schiff base of the above metal complexes of gram-positive bacteria: Staphylococcus aureus and Gram-negative bacteria: Escherichia coli (E. coli) and fungi: Aspergillus niger and Candida albicans showed good antibacterial activity.
