A series of novel lanthanide-based coordination polymers, [Ln(L)(atpa)(H2O)2]n·1.5nH2O (HL = 4-[3-methyl-5-(pyridin-4-yl)-1,2,4-triazol-4-yl]benzoic acid, H2atpa = 2-aminoterephthalic acid and Ln = Tb(1), Dy(2), Ho(3), Er(4), Tm(5), Yb(6)) have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, optical and magnetic measurements. Compounds 1–6 are isomorphous, which can be described as a 2D network based on Ln2(CO2)2 units. The magnetic properties of compound 1 (Tb) show typical antiferromagnetic interaction, while compound 2 (Dy) has ferromagnetic behavior. The room-temperature photoluminescence spectra of 1 exhibit strong characteristic emissions in the visible region, whereas compounds of Dy(2), Er(4) and Yb(6) display NIR luminescence upon irradiation at the ligand band.
