摘　　要：以2,4-二羟基苯甲酸和8-羟基喹啉为配体,以Ni2+作为中心原子,合成了一种新的三元固体配合物H[Ni(C7H4O4)(C9H6NO)]·2.5H2O,并采用元素分析、IR光谱和TG-DSC分析对它的结构进行了表征。结果表明,在该配合物中,2,4-二羟基苯甲酸配体以羧基O原子和一个羟基O原子与中心原子配位,8-羟基喹啉配体以羟基O原子和喹啉N原子与中心原子配位,配合物的配位数为4。In this paper,by using 2,4-dihydroxy benzoic acid and 8-hydroxyquinoline as ligands,Ni2＋ as the central atom,a new ternary solid complex H[Ni（C7H4O4）（C9H6NO）]·2.5H2O was synthesized,and its structure was characterized by elemental analysis,IR spectra,and TG-DSC analysis.The experimental results indicated that in the complex,2,4-dihydroxybenzoic acid ligand coordinated to the central atom with a hydroxyl O atom and a carboxyl O atom;8-hydroxyquinoline ligand coordinated to the central atom with hydroxyl O atom and quinoline N atom,thus the coordination number was 4.
