Abstract

A novel three-dimensional Cd^II coordination polymer, namely, poly[[(μ₃-benzene-1,4-diacetato)(μ₂-benzene-1,4-diacetato)bis{μ₂-bis[4-(2-methylimidazol-1-yl)phenyl]methanone}dicadmium(II)] tetartohydrate], {[Cd(C₁₀H₈O₄)(C₂₁H₁₈N₄O)]·0.25H₂O}_n or {[Cd(PBEA)(MIPMO)]·0.25H₂O}_n, (I), was synthesized by the hydrothermal method using benzene-1,4-diacetic acid (H₂PBEA), bis[4-(2-methylimidazol-1-yl)phenyl]methanone (MIPMO) and Cd(NO₃)₂·6H₂O. The title compound was structurally characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy and thermogravimetric analysis, and exhibits a three-dimensional pillar-layer framework based on Cd^II-PBEA layers and MIPMO pillars, which can be simplified into a pcu topological network. The title compound displays a highly selective and sensitive sensing for Fe³⁺ ions in aqueous solution. In addition, it displays a high photocatalytic activity for the degradation of methylene blue (MB) in water under UV light irradiation.
