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 is further stabilized by interatomic interactions of the types C⋯Cl [C—Cl = 3.284 (2) Å], C—H⋯Cl [C⋯Cl = 3.903 (3) Å] and C—H⋯O [C⋯O = 3.376 (3) Å].

The title complex was prepared by a slightly modified literature procedure (Alessio et al., 1991). The salt [H+(DMSO)2][trans-Ru(DMSO)2Cl4] (1 mmol) was dissolved in a mixture of ethanol (20 ml) and distilled water (0.3 ml). The orange solution was filtered, and then, an aqueous solution (0.3 ml) of NaCl (0.07 g, 2.8 mmol) was added during stirring. The yellow precipitate which formed after several minutes was filtered off, washed with cold acetone, and dried in air (yield 50%). Single crystals were obtained from the filtrate by slow evaporation after several days.
All H-atoms were located in difference maps and refined using a riding model, with C–H distances of 0.98 Å, and with Uiso(H) = 1.5Ueq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title complex, (I), was prepared as a part of our study of simple ruthenium(III) complexes of the composition M[RuCl4(DMSO)2] with the different types of inorganic and organic cations [M]. In the crystal structure of (I), the centrosymmetric [RuCl2(DMSO)Na(DMSO)Cl2Ru] units are present; each ruthenium atom lies on a crystallographic centre of inversion whereas all other atoms lie in general positions. Each of the RuIII atoms is hexacoordinated by two sulphur atoms from two DMSO molecules in apical positions and four chlorido ligands in an equatorial plane (Fig. 1). Each ruthenium atom exists within an octahedral trans-RuCl4S2 donor set.
Both octahedra exhibit similar Ru—S bond lengths [Ru1—S1 = 2.3350 (5) and Ru2—S2= 2.3373 (6) Å] in contrast to the Ru—Cl bond lengths, which exhibit similar values in the Ru1 octahedron [2.3551 (5) and 2.3509 (5) Å] but differ significantly in the Ru2 octahedron [2.3353 (6) and 2.3663 (6) Å]. The Ru—Cl bond lengths within the [RuCl2(DMSO)Na(DMSO)Cl2Ru] unit do not differ markedly from those observed in Na[trans-RuCl4(DMSO)(pyr)].DMSO, where pyr = 1,4-pyrazine, [Ru—Cl = (2.3395 (8) - 2.3754 (7) Å] (Anderson et al., 2007) and in Na2[{trans-RuCl4(DMSO)}2(µ-pyrimidine)], where the Ru—Cl bond lengths are in the range of 2.338 (2) - 2.361 (2) Å (Iengo et al., 1999), while the Ru—S distances in (I) are slightly longer than those observed in the above-mentioned complexes (Ru—S are in the range of 2.281 (2) - 2.3027 (7) Å).
The Na cation has six atoms in its closest octahedrally coordinated environment with the resulting Cl3O3 donor set and it is surrounded by six donor interactions, represented by dashed lines (Figs. 1 and 2). The distance between the two nearest Na atoms equals 3.4968 (19) Å. The distances of the Na—O and Na—Cl donor interactions vary from 2.2974 (18) to 2.4155 (18) Å, and from 2.7773 (11) to 2.9374 (10) Å, respectively. Similar values of the Na—O distances [2.272 (4) - 2.418 (4) Å] were found in Na[trans-RuCl4(DMSO)(NH3)].DMSO (Alessio et al., 1993) and similar Na—Cl distances [2.776 (2) - 2.922 (2) Å] were observed in Na[trans-RuCl4(DMSO)(pyr)].DMSO (Anderson et al., 2007).
The trans-[Ru(DMSO)2Cl4] complex anion is connected to four sodium cations, two DMSO molecules and four chlorido ligands into infinite two dimensional array in the ab plane (Fig. 2). The crystal strucure of (I) is furter stabilized by non-bonding interactions of the C···Cl type [C4···Cl3ii is 3.284 (2) Å (ii = x, y+1, z)], which connect two Ru2 anions in the b direction (Fig. 2). The planes are cross connected, in the c direction, by the weak C···Cl [C3—Cl4vii is 3.903 (3) Å] and C—H···O [C1···O2vii is 3.376 (3) Å (vii = x, 1/2-y, -1/2+z)] type interactions (Fig. 3).
