Four novel organodisulfonate coordination polymers ranging from 0D cluster, 1D chain, 2D layer to 3D framework, {[Eu 2(phen) 4(nds) 2(OH) 2(H 2O) 2]·2H 2O} n ( 1), {[Eu(phen) 2(nds) 0.5(OH)(H 2O)]·0.5nds} n ( 2), {[Eu 2(phen) 4(nds) 3(H 2O) 2]·7H 2O} n ( 3), {Eu(phen)(nds)(OH)} n ( 4) (nds = 2,6-naphthanlenedisulfonate; phen = 1,10-phenanthroline), were synthesized by tuned stoichiometric ratio of the reactants and characterized by single crystal X-ray diffraction, elemental analysis, IR and thermogravimetric analysis. These complexes display a broad and strong ligand-centered luminescent emission band, and all of them have long luminescence lifetimes at millisecond order. Four novel organodisulfonate coordination polymers ranging from 0D cluster, 1D chain, 2D layer to 3D framework were synthesized by tuned stoichiometric ratio of the reactants and characterized by single crystal X-ray diffraction, elemental analysis, IR and thermogravimetric analysis, providing example of structure diversities exhibiting different luminescent properties through the same reactants. [Display omitted] ► Four novel organodisulfonate complexes have been synthesized. ► The only difference among four compositions is the stoichiometric ratio of the reactants. ► Structural diversities exhibit different luminescent properties.
