چکیده
The title compound, [Cd(C(8)H(8)O(5))(C(3)H(4)N(2))(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 penta-gonal-bipyramidal configuration by five O atoms from carboxyl-ate 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-H⋯O and C-H⋯O hydrogen-bonding and C-H⋯π inter-actions.
