The structure of the title compound, [NaRuCl4(C2H6OS)2]n, comprises centrosymmetric [RuCl2(DMSO)Na(DMSO)Cl2Ru] units (DMSO is dimethyl sulfoxide, C2H6OS), with two Ru atoms, each lying on a crystallographic centre of inversion, connected via Na atoms, DMSO and chloride ligands into a two-dimensional (110) array. Both RuIII atoms are octahedrally coordinated by four chloride ligands in the equatorial plane and by two DMSO molecules in apical positions within a RuCl4S2 donor set. The Na atom is surrounded by three chloride anions and three O atoms derived from three DMSO molecules, with the resulting Cl3O3 donor set defining an octahedron. The crystal structure is further stabilized by interatomic interactions of the types CCl [C-Cl = 3.284 (2) Å], C-HCl [CCl = 3.903 (3) Å] and C-HO [CO = 3.376 (3) Å].
