Abstract

In the title compound, [Cd(C6H4O8S2)(C12H8N2)2(H2O)]·H2O, each CdII ion is coordinated by four N atoms [Cd—N = 2.310 (7)–2.341 (7) Å] from two 1,10-phenanthroline ligands, one O atom [Cd—O = 2.300 (6) Å] from a 4,5-dihydroxybenzene-1,3-disulfonate ligand and one aqua O atom [Cd—O = 2.288 (7) Å] in a distorted octahedral geometry. The crystal packing exhibits intermolecular O—H⋯O and C—H⋯O hydrogen bonds and π–π interactions evidenced by relatively short distances [3.525 (5)–3.937 (6) Å] between the centroids of the six-membered rings of neighbouring molecules.
