OBJECTIVE: To study the coordination modes of carboxyl and phenanthroline in rare earth complexes by using spectroscopic techniques. Methods: The Eu (p ABA) 3 · phen · 1.5H 2 O complex was synthesized (p ABA = p-aminobenzoate; phen = phenanthroline). The infrared and Raman spectra of the complex were measured. Spectrum identification. Results: The carboxyl and phenanthroline in the Eu (p ABA) 3 · phen · 1.5H 2 O complex all formed coordination bonds with Eu 3+ ions. Conclusion: It is a good method to study the coordination mode of ligands by using the spectroscopic technique.
