A novel three-dimensional Cd^II coordination framework, namely, poly[{μ-bis[4-(2-methylimidazol-1-yl)phenyl] ether-κ²N³:N^3′}(μ-naphthalene-1,4-dicarboxylato-κ³O¹:O⁴,O^4′)cadmium(II)], [Cd(C₁₂H₆O₄)(C₂₀H₁₈N₄O)]_n or [Cd(1,4-NDC)(BMIOPE)]_n, where 1,4-H₂NDC is naphthalene-1,4-dicarboxylic acid and BMIOPE is bis[4-(2-methylimidazol-1-yl)phenyl] ether, has been prepared and characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy and thermogravimetric analysis. The compound displays a novel fourfold interpenetrating diamond-like network. In addition, it not only shows a strong fluorescence emission in the solid state, but also exhibits excellent photocatalytic activity for the degradation of methylene blue (MB) at room temperature.
