| 摘 要： | 在乙醇溶液中合成了稀土离子(RE=Tb，Eu，Sm，Nd)与2-羟基-3-萘甲酸(HL)、邻菲咯啉(phen)固体配合物。通过元素分析、红外光谱、紫外光谱、差热-热重分析，确定了配合物的组成为REL4·phen2·Na·H2O。初步研究了这些配合物的谱学性质并推测出羧基(—COO—) 与稀土离子和钠离子属于桥式配位, 形成了链状结构的化合物。其中钠离子和稀土离子分别为六配位和八配位模式。

| 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 x phen2 x Na x 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. |
