Aim: Using spectrum technique to study coordinate mode of the carboxyl and 1,10 phenanthroline with the Eu 3+ in the coordination compound. Methods:Compound Eu(p ABA) 3·phen·1.5H 2O (p ABA: p aminobenzoate; phen: 1,10 phenanthroline) was synthesized. FT IR spectrum and FT Raman spectrum of Eu(p ABA) 3·phen·1.5H 2O complex was recorded,and the data was analyzed. Results: The carboxyl and 1,10 phenanthroline was proved to connect with the Eu 3+ in the Eu(p ABA) 3·phen·1.5H 2O.Conclusion: It is a good method to study coordinate mode of the carboxyl and 1,10 phenanthroline with the Eu 3+ in the coordination compound by spectrum technique.
