Abstract

Abstract : A zinc(II) compound, prepared by the reaction of Zn(NO3 )2 ·6H2 O with naphthalene‐2, 6‐dicarboxylic acid and 1, 3‐bis(2‐methyl‐1 H ‐imidazol‐1‐yl)benzene in a mixture of H2 O and dimethylformamide, possesses a twofold interpenetrating two‐dimensional network. The compound exhibits strong fluorescence emissions and a high photocatalytic activity for the degradation of Rhodamine B (RhB) under UV‐light irradiation. Abstract : A novel twofold interpenetrating two‐dimensional (2D) Zn II coordination framework, poly[[(μ‐1, 3‐bis(2‐methyl‐1 H ‐imidazol‐1‐yl)benzene‐κ 2 N 3 : N 3 )(μ‐naphthalene‐2, 6‐dicarboxylato‐κ 2 O 2 : O 6 )zinc(II)] dimethylformamide monosolvate], {[Zn(C12 H6 O4 )(C14 H14 N4 )]·C3 H7 NO} n or {[Zn(1, 3‐BMIB)(NDC)]·DMF} n (I), where H2 NDC is naphthalene‐2, 6‐dicarboxylic acid, 1, 3‐BMIB is 1, 3‐bis(2‐methyl‐1 H ‐imidazol‐1‐yl)benzene and DMF is dimethylformamide, was prepared and characterized through IR spectroscopy, elemental analysis, thermal analysis and single‐crystal X‐ray diffraction. Single‐crystal X‐ray diffraction analysis revealed that (I) exhibits an unusual twofold interpenetrating 2D network. In addition, it displays strong fluorescence emissions and a high photocatalytic activity for the degradation of Rhodamine B (RhB) under UV‐light irradiation.
