Poly[bis­(1 H-imidazole)(μ ₃-7-oxabicyclo­[2.2.1]heptane-2,3-dicarboxyl­ato)cadmium(II)]

Abstract

The title compound, [Cd(C ₈H ₈O ₅)(C ₃H ₄N 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 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—H⋯O and C—H⋯O hydrogen-bonding and C—H⋯π inter­actions.
