Abstract A series of rare-earth compound RE2L2(HL)2(H2O)6·2H2O (RE=La, Nd, Eu, Tb, Er, Y) containing 3-nitrophthalic acid(H2L) ligand were synthesized from ethanol-water solution,and characterized and investigated by the element analysis, infrared and ultraviolet absorption spectra and different thermal-thermogravimetric analysis. The results of the spectroscopic analysis were conformed to the crystal structures determined by X-ray diffraction, showing that the carboxylate (—COO-) and carboxyl (—COOH) groups of the ligand link to the rare-earth ions by bridging and terminal mode respectively. Two rare-earth ions were linked by two di-deprotonated ligand L2-in bridging-chelating mode to form a dinuclear structure, and coordinated by the other two mono-deprotonated ligands HL-in terminal chelating mode using their carboxylate (—COO-) and carboxyl (—COOH) group together, respectively. The IR spectra shows the existence of the carboxylate (—COO-) and carboxyl (—COOH) group and the hydrogen bond interactions between the carboxyl (—COOH) group and crystal water. The DTA-TGA data were consistent with the composition of compounds, exhibiting an endothermic peak of the loss of the crystal and coordinated waters at about 150 ℃ and two exothermic peaks of the oxidation and decomposition of ligands in the rang of about 340 to 460 ℃.
