The crystal structure of the title complex, [K2 (5-nbdc)2Cd(Ⅱ)·imH· H2O]∞ (5-nbdc=5-nitro-1,3-benzenedicarbonate, imH=imidazole) has been determined by X-ray diffraction analysis. The crystal data are: tetragonal, space group P41, Mr=694.93 for CdC19H12N4O13K2, a=1.018 6(10) nm, b=1.018 6(10) nm, c=2.4367(5) nm; Z=4,mensional framework, in which adjacent Cd(Ⅱ) ions are bridged byμ-O4-5-nitro-1,3-benzenedicarbonate groups forming one-dimensional chains that are further linked byμ-O3-5-nitro-1,3-benzenedicarbonate groups into twodimensional anion rectangle sheets with large 32-membered rings. The strong π-π stacks of the benzene rings link these adjacent sheets into a three-dimensional van der Waals network. CCDC: 245527.
