Abstract: The title compound, [Cd(C₈H₈O₅)(C₃H₄N₂)₂]_n, was synthesized by the reaction of 7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylic anhydride, cadmium acetate and imidazole. The Cd^II atom is seven-coordinated in a distorted pentagonal-bipyramidal configuration by five O atoms from carboxylate groups of three 7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylate ligands and two N atoms from two imidazole ligands. The crystal structure is stabilized by N-HO and C-HO hydrogen-bonding and C-H interactions.
