Abstract
The two compounds containing disulfonate groups A-2,5-DSA·(Hphen)2·2H2O(1) and [Co(phen)2(H2O)2]·(A-2,5-DSA)·3H2O(2)(A-2,5-DSA=aniline-2,5-disulfonate anion, phen=1,10-phenanthroline) were synthesized by the slow solvent evaporation method in water. In the compound 1, the adjacent protonated 1,10-phenanthroline cation(Hphen)+reversely stack together. The water molecules connect to the(Hphen)+cations and aniline-2,5-disulfonate anions to form two-dimensional layered structure through the hydrogen bonds. In the compound 2, the cobalt ion coordinates with two 1,10-phenanthroline and two water molecules to generate the [Co(phen)2(H2O)2]2+cation. The three free water molecules connect to the [Co(phen)2(H2O)2]2 +cations and aniline-2,5-disulfonate anions to form three-dimensional network structure through the hydrogen bonds. In the two compounds, the aniline-2,5-disulfonate anions only balance the charges. The compounds exhibit the luminescence properties with emission maximum at 601 nm and 441 nm at room temperature, respectively. CCDC: 978180, 1; 978179, 2.
