摘　　要：本文合成了镧、铈、镨的硼合扁桃酸配合物,并进一步用硼合扁桃酸镧同喹啉(qui)、邻菲罗啉(phen)、联吡啶(dip)等含氮配体作用制备出了三元配合物.用化学分析、红外光谱、氢核磁共振谱、紫外—可见光谱.摩尔电导及热谱等物理化学测试手段,确定了这些化合物的组成和成键情况,并对其某些物理化学性质进行了研究.The title complexes have been synthesized and characterized. The result show that their composition are Ln(HL)2[(HO)2BL] · H2O (Ln = La, Ce, Pr) and La(HL)2[(HO)2BL] · Q (Q = qui, dip and phen). IR and HNMR spectra indicate that in the complexes the amygdalinic acid combined with Ln3+ by two ways: carboxylate and amygdalinic acid-borate. Electronic spectra and molar conductances show that the compounds are mainly ionic and existed in the form of 1 : 1 electrolyte in water, but low molar conductances in DMF and DMSO are corresponded with non-electrolytic labeling.
