合成了２１种金属离子Ｌａ（Ⅲ），Ｃｕ（Ⅱ），Ｎｉ（Ⅱ）和Ｃｏ（Ⅱ）与氨基苯甲酸及吡啶单羧酸的化合物，其中１４种是尚未报道过的新化合物．通过元素分析、红外光谱、Ｘ－射线粉末衍射，ＴＧ－ＤＴＧ等表征了产物的结构特征和热分解过程．结果表明，配体酸中氨基和羧基的相对位置影响着配体酸与金属离子的反应能力和反应产物的热稳定性 21 compounds of La (Ⅲ), Cu (Ⅱ), Ni (Ⅱ) and Co (Ⅱ) with aminobenzoic acid and pyridine monocarboxylic acid were synthesized, of which 14 were new compounds which had not been reported yet. The structure and thermal decomposition of the product were characterized by elemental analysis, IR, X-ray powder diffraction and TG-DTG. The results showed that the relative positions of the amino and carboxyl groups in the ligand acid affected the ability of the ligand to react with the metal ion and the thermal stability of the reaction product
