摘要: 采用溶剂热法合成了一例新型层状磁性镱配合物Yb(HCOO)(C2O4)(1,10-phen) (1,10-phen = 邻菲罗啉),并利用X射线衍射、红外、热重和磁化率等测试对其晶体结构和磁性性能进行了表征.单晶结构分析表明,该配合物中磁性离子Yb3+通过甲酸根与草酸根连接形成四方磁晶格层,层间通过邻菲罗啉配体隔开.磁性测试结果显示,配合物中Yb3+间以反铁磁相互作用占主导,且在温度低至2 K时未出现长程磁有序.本研究为构筑具有低维磁性的稀土配合物提供了新的合成策略.

Abstract: A novel layered magnetic ytterbium coordination compound, Yb(HCOO)(C2O4)(1,10-phen) (1,10-phen = 1,10-phenanthroline), has been successfully synthesized via a solvothermal method. Its crystal structure and magnetic properties were characterized by X-ray diffraction, infrared spectroscopy, thermogravimetric analysis, and magnetic susceptibility measurements. Single-crystal structure analysis reveals that the magnetic Yb3+ ions are connected by formate and oxalate ligands to form a square magnetic lattice, with adjacent layers separated by 1,10-phen ligands. Magnetic measurements show that the dominate interaction between the Yb3+ ions is antiferromagnetic, and no long-range magnetic order is observed down to 2?K. This study provides a new synthetic strategy for constructing low-dimensional magnetic rare-earth coordination compounds.

Key words: Low-dimensional magnetism, Crystal structure, Ytterbium coordination compound, Solvothermal method
