Abstract: The title complex, {[Mn(C₁₄H₆O₈S₂)(C₁₂H₈N₂)₂]·4H₂O}_n, exhibits a chain-like polymeric structure with 9,10-dioxoanthracene-1,5-disulfonate anions bridging Mn^II atoms in a bis-monodentate mode. The unique Mn^II atom is located on a crystallographic centre of inversion. Four N atoms from two chelating 1,10-phenanthroline ligands and two sulfonate O atoms from two symmetry-related 9,10-dioxoanthracene-1,5-disulfonate anions give rise to a slightly distorted octahedral coordination environment around the Mn^II centre. The centroid of the central ring of the anthraquinone ligand represents another crystallographic centre of inversion. In the crystal structure, interligand - stacking [centroid-to-centroid distances 3.532 (1) and 3.497 (3) Å] and intermolecular O-HO hydrogen-bonding interactions assemble the chains into a three-dimensional supramolecular network.
