摘　　要：用~１ＨＮＭＲ和~１３ＣＮＭＲ对Ｌａ（ＨＳａｌ）_２·ｈｑ（镧－水杨酸－８羟基喹啉）和Ｌａ（ＮｏＡ）_２·ｈｑ（镧－萘氧乙酸－８羟基喹啉）三元配合物的研究结果表明：Ｌａ（ＨＳａｌ）_２·ｈｑ中Ｌａ^（３＋）与Ｈｈｑ上的Ｏ、Ｎ配位，同时Ｈ_２Ｓａｌ中羧基失去质子，与Ｌａ^（３＋）配位，而Ｈ_２Ｓａｌ中羟基未参与配位；Ｌａ（ＮＯＡ）_２·ｈｑ中Ｌａ^（３＋）与Ｈｈｑ上的Ｏ、Ｎ配位，并且使ＨＮＯＡ中羧基失去质子，与Ｌａ（２＋）配位。Ternary complexes of Lanthanum(Ⅲ) with salicylic acid(or naphthyloxyacetic acid )and 8-hydroxyquinoline were synthesized and characterized by elemental analysis,H-NMR and ￣13C-NMR.It is indicated that oxygen and nitrogen atoms of 8-hydroxyquinoline (Hhq) and carboxylate ion of salicylic acid (H2Sal) are coordinated to La(3+),but hydroxy of salicylic acid are uncoordinated in La(HSal)2·hq. It is shown that oxygen and nitrogen atoms of 8-hydroxy-quinuline and Carboxylate ion of naphthyloxyacetic acid (HNOA) are coordinated to La(3+) ion in La (NOA)2·hq.
