合成并表征了双水杨醛缩 1，6-己二胺希夫碱配体(C20H24N2O2，以 L 表示) 与轻稀土 Ln3+的7 种新的固体配合物［LnL2］(NO3)3(Ln=La、Ce、Pr、Nd、Sm、Eu、Gd)。利用元素分析、摩尔电导、红外光谱、电子光谱、X射线衍射物相分析、热分析方法进行表征。中心金属离子 Ln3+与希夫碱配体中的亚胺氮和酚羟基中的氧发生配位，配位数为8。
Seven new solid complexes of light rare earth with schiff base from salicylaldehyde and 1,6-hexanediamine were synthesized and characterized by elemental analysis, molar conductance, IR,UV,XRD,TG-DTG. The compositions of the complexes were confirmed to be ［LnL2］(NO3)3(Ln=La,Ce,Pr,Nd,Sm,Eu,Gd);L=bis(salicylaldehyde)-1,6-hexanediamine,C20H24N2O2). Every central Ln3+ ion in the complexes coordinates with schiff base ligands both via four nitrogen atoms of imido groups and four oxygen atoms of the phenol hydroxy groups. Their coordination numbers are eight.
