Abstract: The title complex, [Cd(C₁₄H₆O₈S₂)(C₁₀H₈N₂)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 octahedral 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-HO hydrogen-bonding contacts and - interactions [centroid-centroid distances = 3.6920 (12) and 3.7095 (12) Å] connect the complex molecules into a three-dimensional supramolecular framework.
