Six novel three-dimensional (3D) lanthanide metal–organic frameworks (LnMOFs), {[Ln2(ispc)3(H2O)3]·mH2O}n (Ln = Pr (1, m = 5); Eu (2, m = 5); Gd (3, m = 4); Tb (4, m = 5); Dy (5, m = 5) and Ho (6, m = 4)), ispc = 3-(4-carboxyphenylsulfonyloxy)-4-methoxybenzoic anion) have been synthesized under hydrothermal conditions. Single crystal X-ray diffraction revealed they are isostructural and crystallize in the triclinic crystal system, space group P. The investigations on luminescent properties and lifetimes of 2 (EuIII), 4 (TbIII), and 5 (DyIII) exhibit characteristic emissions of EuIII, TbIII and DyIII ions and the corresponding luminescent lifetimes are 0.14 ms, 9.93 μs and 1.25 ms, respectively. The different luminescent intensities and lifetimes among them were further discussed. Furthermore, magnetic studies of 1–6 reveal that 3–6 exhibit ferromagnetic coupling, and 5 (DyIII) exhibits remarkably slow magnetic relaxation behavior with the energy barrier ΔE/kB = 49.2 K.

A novel series of lanthanide coordination polymers (Ln-CPs) have been obtained based on mixed ligands, 2-[(4-carboxyphenyl)methoxy]benzoic acid (H2cob) and 1,10-phenanthroline (phen), namely {Ln[(Hcob)(cob)(phen)]n, Ln = La (1), Pr (2), Sm (3), Eu (4)}. Complexes 1–4 were characterized by single crystal X-ray diffraction, elemental analysis, powder X-ray diffraction, infrared spectroscopy and thermogravimetric analysis. Single crystal X-ray diffraction revealed that complexes 1–4 show two-dimensional layer structures. The luminescence properties of complexes 3 and 4 were thoroughly investigated.
