A new microporous coordination polymer [Ca(nbdo)(H 2 O) 2 ] n , constructed by 2‐nitro‐benzene‐1,4‐di(oxyace‐tate), was obtained by a slow evaporation method and characterized by elemental analysis, FT‐IR, single‐crystal X‐ray diffraction, DSC, TG‐DTG and fluorescent spectral analysis. The crystal structure reveals that there is 1‐D microporous channel, which is bridged by four kinds of hydrogen bonds to generate a 3‐D supramolecular network. The thermal analysis of the complex shows that it began to lose water molecules at 375 K, and when the temperature was up to 550 K the framework of the coordination polymer began to collapse. The luminescence property was investigated and the complex shows photoluminescence in the solid state at room temperature, excited at 320 nm.
