A novel two‐dimensional Cd II coordination framework, poly[[[μ‐1,3‐bis(2‐methyl‐1 H ‐imidazol‐1‐yl)benzene‐κ 2 N : N ′](μ‐1,3‐phenylenediacetato‐κ 4 O , O ′: O ′′, O ′′′)cadmium(II)] dihydrate], {[Cd(C 10 H 8 O 4 )(C 14 H 14 N 4 )]·2H 2 O} n or {[Cd(PDA)(1,3‐BMIB)]·2H 2 O} n [1,3‐BMIB is 1,3‐bis(2‐methyl‐1 H ‐imidazol‐1‐yl)benzene and H 2 PDA is 1,3‐phenylenediacetic acid], has been prepared and characterized using IR, elemental analysis, thermal analysis and single‐crystal X‐ray diffraction, the latter revealing that the compound is a (4,4) grid coordination polymer with layers oriented parallel to the bc crystal planes. In the crystal, adjacent layers are further connected by O—H…O and C—H…O hydrogen bonds, forming a three‐dimensional structure in the solid state. In addition, the compound exhibits strong fluorescence emissions and shows photocatalytic activity for the degradation of methylene blue in the solid state at room temperature.
