A novel two‐dimensional (2D) Zn II coordination framework, poly[[μ‐1,3‐bis(2‐methyl‐1 H ‐imidazol‐1‐yl)benzene](μ‐5‐nitrobenzene‐1,3‐dicarboxylato)zinc(II)], [Zn(C 8 H 3 NO 6 )(C 14 H 14 N 4 )] n or [Zn(NO 2 ‐BDC)(1,3‐BMIB)] n [1,3‐BMIB is 1,3‐bis(2‐methyl‐1 H ‐imidazol‐1‐yl)benzene and NO 2 ‐H 2 BDC is 5‐nitrobenzene‐1,3‐dicarboxylic acid], has been prepared and characterized by IR, elemental analysis, thermal analysis and single‐crystal X‐ray diffraction. Single‐crystal X‐ray diffraction analysis revealed that the compound is a new 2D polymer with a 6 3 topology parallel to the (10) crystal planes based on left‐handed helices, right‐handed helical NO 2 ‐BDC–Zn chains and [Zn 2 (1,3‐BMIB) 2 ] n clusters. In the crystal, adjacent layers are further connected by C—H…O hydrogen bonds, C—H…π interactions, C—O…π interactions and N—O…π interactions to form a three‐dimensional structure in the solid state. In addition, the compound exhibits strong fluorescence emissions in the solid state at room temperature.
