Abstract

Abstract : A cadmium(II) compound prepared by reaction of Cd(NO3 )2 ·6H2 O with 1, 3‐phenylenediacetic acid and 1, 3‐bis(2‐methyl‐1 H ‐imidazol‐1‐yl)benzene in H2 O, possesses a new (4, 4) two‐dimensional Cd II coordination polymeric structure parallel to the bc plane. The compound exhibits strong fluorescence emissions and a highly photocatalytic degradation activity for the degradation of methylene blue in the solid state at room temperature. Abstract : 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(C10 H8 O4 )(C14 H14 N4 )]·2H2 O} n or {[Cd(PDA)(1, 3‐BMIB)]·2H2 O} n [1, 3‐BMIB is 1, 3‐bis(2‐methyl‐1 H ‐imidazol‐1‐yl)benzene and H2 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.
