摘　　要：首次在室温条件下通过固相反应制得了镧稀土水杨酸 8-羟基喹啉三元配合物 La(Hsal) 2 (hq)(hq=C9H6NO-;Hsal-=C7H5COO-)。采用元素分析、红外光谱、X射线粉末衍射、热重 -差热分析等手段对配合物进行了表征。同时还初步分析了固相反应的机理。抑菌实验表明该配合物对大肠杆菌、金黄色葡萄球菌、白色念珠菌。In this paper, ternary rare earth complexes La(Hsal) 2(hq) (hq=C 9H 6NO -;Hsal -=C 7H 5COO -) was firstly synthesized by solid state reaction of rare earth chloride with sodium salicylate and 8 hydroxyquinoline at room temperature. The complexes were characterized by elemental analyses, X ray powder diffraction, FT IR and TG DTA. Antibacterial test displayed that the complexes have strong antibacterial activity against Escherichia coli, Staphylococcus aureus, Candida albican, Bacillus subtilis.
