The title compound, catena-poly[[tetrakis("-decanoato- 2O:OH )-diruthenium(II,III)(RuÐRu)]-"-octanesulfonato- 2O:O H ],[Ru2(C10H19O2)4(C8H17O3S)], is an octanesulfonate derivativeof the mixed-valence complex diruthenium tetradecanoate.The equatorial carboxylate ligands are bidentate, bridging twoRu atoms to form a dinuclear structure. Each of the twoindependent dinuclear metal complexes in the asymmetricunit is located at an inversion centre. The octanesulfonateanion bridges the two dinuclear units through axial coordina-tion. The alkyl chains of the carboxylate and sulfonate ligandsare arranged in a parallel manner. The global structure can beseen as infinite chains of polar moieties separated by a doublelayer of non-polar alkyl groups, without interdigitation of thealkyl chains.
