Abstract

Abstract: The preparation for binary and ternary solid complexes of rare earth Eu³⁺ with pyridine-2,6-dicarboxylic acid(H₂DPC) and 1,10-Phenanthroline are reported in this article. Their compositions confrmed by elemental analysis, being binary Na₃[Eu(DPC)₃]·2H₂O and ternary NaEu(DPC)₂·Phen·4H₂O. Their structures were studied by ¹H、¹³C、¹⁴N N-MR and ER spectra. The pyridine-2,6-dicarboxylic acid is a tridentate ligand. Two coordination numbers of europium are nine and eight in binary and ternary complexes respectively.

Key words: Rare earth Eu, Pyridine-2,6-dicarboxylic acid, 1,10-phenanthroline, NMR, IR
