The title compound, [RuCl2(C9H12)(C2H6OS)], features a planar [maximum deviation = 0.0075 (17) Å] η6-bound mesitylene ligand and a dimethyl sulfoxide ligand coordinated via the S atom. The overall complex geometry about the Ru(II) atom is best described as a piano-stool configuration.

[{RuCl2(C6H3Me3)}2] (175 mg, 0.30 mmol) was dissolved in DMSO (12 ml). The solution was heated to 100 °C for 45 min and a small amount of ruthenium black was removed by filtration. The dark red solution was concentrated in vacuo until the formation of crystals was observed. The product was isolated by filtration and dried in vacuo. A second crop of material was obtained from the mother liquor by layering with toluene. Yield: 150 mg (68%) of red crystals. Crystals suitable for X-ray diffraction were obtained by slow evaporation of a saturated DMSO solution.
Hydrogen atoms were placed on idealized positions and refined using a riding model with Uiso(H) = 1.2 × Ueq(C) (1.5 for methyl groups) and C–H bond lengths of 0.95 Å for aromatic protons and 0.98 Å for methyl groups.
Reflexes 0 1 1 and -1 1 1 were omitted from the
because they were effected by the diffractometer's beamstop. Reflex -5 0 3 was also omitted because of its exceptionally large deviation from the calculated intensity.Data collection: X-AREA (Stoe & Cie, 2001); cell

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s 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 > 2σ(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. |

Complexes of the type [{RuCl2(arene)}2] are valuable starting materials for the preparation of ruthenium(II) complexes because they allow facile ligand substitution. During our investigations concerning the arene substitution behaviour of such complexes, we found that [{RuCl2(C6H3Me3)}2] readily reacts with dimethylsulfoxide, yielding the monomeric title compound [RuCl2(DMSO)(C6H3Me3)]. Similar reactivity has been reported for the corresponding benzene and p-cymene complexes (Ogata et al., 1970; Chandra et al., 2002).
The overall complex geometry of the title compound is best described as a piano-stool configuration. Another possible description is that of an octahedral d6 low-spin complex with the arene ligand occupying three fac-oriented coordination sites. The angles between the monodentate chloro and DMSO ligands are thus close to 90° (Table 1). The planar, η6-bound mesitylene ligand shows almost equal Ru–C distances of 2.1978 (15) to 2.2219 (16) Å. Dimethylsulfoxide is coordinated via sulfur as usual for complexes without sufficient steric bulk to force O-coordination. All numerical parameters concerning the molecular geometry are similar to those observed for the corresponding p-cymene complex (Chandra et al., 2002).
