ABSTRACT: 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?? inter-actions.

Two O atoms link two Cd(II) atoms, forming a dinuclear center: the Cd-O-Cd bridging angle is 110.19?(6)°. The polymeric structure extends along [100] and is linked by inter-molecular O-H?O hydrogen bonds involving the solvent water molecule. Extensive ?-? stacking exists between 2,2-bypiridine ligands along [010] with centroid-centroid distance of 3.650?(2)?Å

Project description:The title polymer, [Zn(3)(C(8)H(8)O(5))(2)(C(3)H(3)N(2))(2)(C(3)H(4)N(2))(2)](n), was formed by the reaction of zinc acetate with imidazole and 7-oxabicyclo-[2.2.1]heptane-2,3-dicarboxylic anhydride (norcan-tharidine). One of the two crystallographically unique Zn(II) atoms is four-coordinated by three N atoms of three imidazole ligands, two of which are deprotonated, and by one carboxyl-ate O atom of the demethyl-cantharate anion. The second Zn(II) atom is situated on an inversion centre and is six-coordinated by the bridging O atoms of two symmetry-related demethyl-cantharate anions and by four carboxyl-ate O atoms of the corresponding carboxyl-ate groups. The polymeric crystal structure is additionally stabilized by N-H?O hydrogen bonding between the imidazole ligands and carboxyl-ate O atoms.
