Abstract:

A novel layered magnetic ytterbium coordination compound, Yb(HCOO)(C2O4)(1,10-phen)(1,10-phen= 1,10-phenanthroline), was synthesized via a solvothermal method. Its crystal structure and magnetic properties were characterized by means of X-ray diffraction(XRD), infrared spectroscopy(IR), thermogravimetric analysis(TGA), 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 dominant 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.
