CatenaPoly[[bis-(2,2′-bipyridine-k2 N,N′)cadmium(II) ] -μ-9,10-dioxoanthracene-1,5-disulfonato-κ2 O 1:O 5]

The title complex, [Cd(C14H6O8S 2)(C10H8N2)2] n , exhibits a chain-like polymeric structure with 9,10-dioxoanthracene-1,5-disulfonate anions bridging CdII atoms in a bis-monodentate mode. The CdII 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.
