title: catena-Poly[[bis-(2,2'-bipyridine-κN,N')cadmium(II)]-μ-9,10-dioxo-anthracene-1,5-disulfonato-κO:O].
abstract: The title complex, [Cd(C(14)H(6)O(8)S(2))(C(10)H(8)N(2))(2)](n), exhibits a chain-like polymeric structure with 9,10-dioxoanthracene-1,5-disulfonate anions bridging Cd(II) atoms in a bis-monodentate mode. The Cd(II) atom shows a distorted octa-hedral environment, with four N atoms from two chelating 2,2'-bipyridine ligands forming the equatorial plane and two sulfonate O atoms from two 9,10-dioxoanthracene-1,5-disulfonate anions occupying the apical positions. Weak C-H⋯O hydrogen-bonding contacts and π-π inter-actions [centroid-centroid distances = 3.6920 (12) and 3.7095 (12) Å] connect the complex mol-ecules into a three-dimensional supra-molecular framework.
