Abstract：The solid rare-earth (RE=Tb, Eu, Sm, Nd) compounds with 3-hydroxyl-2-naphthalinic acid (L) and phenanthroline (phen) were synthesized in ethanol solution in the present work. Their compositions were determined to be REL4·phen2·Na·H2O by the element analysis, infrared and ultraviolet absorption spectra, and DTA-TGA, respectively. The spectral properties of the compounds were studied tentatively, and the coordination mode of carboxyl group was deduced to be bridged style to chelate the rare-earth and sodium ions to form an infinite chain structural complex. The sodium and rare-earth ions are six-coordinated and eight-coordinated geometry respectively.
