Four rare earth organodisulfonate coordination polymers, {[Tb2(phen)4(nds)3(H2O)2]·4H2O}n (1), {[Ln(phen)(nds)(OH)]}n[Ln = Sm (2), Nd (3)], {[Tb(phen)2(nds)0.5(OH)·H2O]·(nds)0.5}n (4), were synthesized under the solvothermal conditions by using ligands 2,6-naphthalenedisulfonate (L = nds) and 1,10-phenanthroline (L′ = phen). Single-crystal X-ray diffraction reveals that compounds 1 and 4 exhibit different 1-D and 2-D crystal structures just owing to the single difference of stoichiometric ratio of the reactants in the synthesis process. Compounds 2 and 3 show 3-D structures with similar Ln coordination mode. Besides, the photoluminescent property in solid state of 1 was investigated in detail.
