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。 A new ternary complex H [Ni (C7H4O4) (C9H6NO)] · 2.5H2O was synthesized by using 2,4-dihydroxybenzoic acid and 8-hydroxyquinoline as ligands with Ni2 + as the central atom. Its structure was characterized by elemental analysis, IR spectrum and TG-DSC. The results show that in the complex, 2,4-dihydroxybenzoic acid ligand with a carboxyl O atom and a hydroxyl O atoms with the central atom coordination, 8-hydroxyquinoline ligand with hydroxyl O atoms and quinoline N atoms Coordination with the central atom, the coordination number of the complex is 4.
