The compound was synthesized by dissolving rhodium(III) chloride (Aldrich, 98%) in excess of dimethyl sulfide (Merck, 99%) at 343 K followed by a 12 h reflux. The mixture was then cooled to room temperature. Crystals were obtained after the evaporation of the solvent.
The Flack parameter was refined from 1283 Friedel pairs.
The H atoms are in calculated positions and constrained to ride on the parent C atoms with the C—H distance 0.96 Å and Uiso(H) = 1.5 Ueq(C).
One aim of the current study is to investigate the nature of Rh—S bonds and to make a comparison with analogous compounds such as the sulfoxide complexes (Abbasi, et al., 2006; Calligaris, 2004; Alessio, 2004). Interest in the use of the dimethyl sulfide ligand arises from its involvement in the homogeneous hydrogenation of olefinic substrates (James et al. 1968).
The rhodium(III) ion is octahedrally coordinated by the sulfur atoms of the three dimethyl sulfide molecules, and three chlorine atoms in a mer octahedral configuration (Fig. 1). The Rh—S bond distance in for the sulfur trans to the chlorine [2.328 (1) Å] is longer than that cis to the chlorine [2.283 (1) Å], which indicates strongr π-back bonding from metal to sulfur (Abbasi et al., 2006).

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