چکیده
The title compound, {[Cd(C(8)H(8)O(5))(C(10)H(8)N(2))]·H(2)O}(n), was obtained by the reaction of cadmium acetate with 2,2'-bi-pyridine and 7-oxabicyclo-(2.2.1)heptane-2,3-dicarb-oxy-lic anhydride. The Cd(II) atom is seven-coordinated in a distorted penta-gonal-bipyramidal configuration, defined by five O atoms from the carboxyl-ate groups of three 7-oxabicyclo-[2.2.1]heptane-2,3-dicarboxyl-ato ligands and two N atoms from the 2,2'-bipyridine ligand. 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 π-π stacking exists between 2,2-bypiridine ligands along [010] with centroid-centroid distance of 3.650 (2) Å
