Five ternary solid complexes of rare earth with alpha-naphthoic acid (HNaP) and 1,10-phenanthroline (Phen) were prepared. These complexes all have the composition of RE(Nap)3.phen (RE3+ = Y, La, Eu, Tb, Dy). IR and Raman spectra were investigated. Assignment of complex bands were made by searching group vibration frequencies. Vibrational spectra indicate that carboxylate ions in the alpha-naphthoate take the bidentate coordination modes and the nitrogen atoms in 1,10-phenanthroline are coordinated and format five number chelate ring.
制备了稀土与α-萘甲酸（HNaP）和1,10-菲啰啉（Phen）的五种三元固体配合物。这些配合物均具有RE(Nap)3·phen的组成（RE3+ = Y、La、Eu、Tb、Dy）。研究了红外光谱和拉曼光谱。通过搜索基团振动频率对配合物谱带进行了归属。振动光谱表明，α-萘甲酸盐中的羧酸根离子采取双齿配位模式，1,10-菲啰啉中的氮原子发生配位并形成五元螯合环。
