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=2.436 7(5) nm; Z=4, V=2.528 2(6) nm3, F(000)=1 376, Dc=1.826 Mg·m-3, μ=1.267 mm-1. The title polymeric complex exhibits a two-dimensional framework, in which adjacent Cd(Ⅱ) ions are bridged by μ-O4-5-nitro-1,3-benzenedicarbonate groups forming one-dimensional chains that are further linked by μ-O3-5-nitro-1,3-benzenedicarbonate groups into two-dimensional 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.
