The asymmetric unit of the title compound, [RuCl₂(C₆H₆)(C₁₈H₂₇P)]·1.5C₆H₆, contains one molecule of the Ru^II complex and one and a half solvent molecules as one of these is located about a centre of inversion. The Ru^II atom has a classical three-legged piano-stool environment being coordinated by an η⁶-benzene ligand [Ru—centroid = 1.6964 (6) Å], two chloride ligands with an average Ru—Cl bond length of 2.4138 (3) Å and a dicyclohexylphenylphosphane ligand [Ru—P = 2.3786 (3) Å]. The effective cone angle for the phosphane was calculated to be 158°. In the crystal, weak C—H⋯Cl hydrogen bonds link the Ru^II complexes into centrosymmetric dimers. The crystal packing exhibits intra- and intermolecular C—H⋯π interactions resulting in a zigzag pattern in the [101] direction.

Comment top

The activity of the half-sandwich Ru(II)-arene complexes are well known in the catalytic transfer hydrogenation of carbonyl compounds (Chen et al., 2002; Crochet et al., 2003; Aydemir et al., 2011; Wang et al., 2011) and for ring-opening metathesis polymerization (Stumpf et al., 1995). Reported here is the η⁶-Ru compound containing the phosphane, PCy₂Ph, where Cy = C₆H₁₁ and Ph = C₆H₅ as part of our ongoing structural investigation into these type of complexes.

The title compound crystallizes in the triclinic space group P1 (Z=2), with its molecules adopting a classical three-legged piano-stool environment observed for these type of complexes. Each Ru complex co-crystallizes with sesqui benzene solvate molecules due to one of the solvate being situated on an inversion centre (see Fig. 1). The coordination sphere of the ruthenium is occupied by a benzene, dicyclohexylphenylphosphane and two chloride atoms. The distance between Ru and the centroid of the π-bonded η⁶-benzene ligand is 1.6964 (6) Å and the mean Ru—C bond distance is 2.2099 (13) Å. The coordination of the remaining ligands to the Ru atom shows a slight deviation from the typical octahedral geometry with Cl—Ru—Cl = 88.07 (11) and Cl—Ru—P = 87.12 (11), 90.97 (2)°. The bond distances of Ru—P = 2.3786 (3) and Ru—Cl(avg.) = 2.4138 (3) Å are within normal ranges (Allen, 2002).

The steric demand of phosphane ligands is usually described with the use of the Tolman cone angle model (Tolman, 1977). In the present study we make use of an adaptation of this model whereby the geometry obtained from the title compound (and adjusting the Ru—P bond distance to 2.28 Å) is used to calculate an effective cone angle (Otto, 2001). The value obtained with this method is 158°, which is marginally smaller that the average effective cone angle value calculated from literature observations of the phosphane ligand. Data extracted from the Cambridge Structural Database (Allen, 2002) shows an average cone angle of 165° for the phosphane from 31 hits, containing 45 useable observations with a standard deviation of ±6° and a spread from 148° to 180°.

The slightly smaller cone angle value obtained for the phosphane ligand in the title compound could be due to a crowded metal coordination environment as well as several C–H···Cl and C–H···π interactions that are observed (see Fig. 2, Table 1 for a graphical representation of the interactions).

Special details top

Experimental. The intensity data was collected on a Bruker Apex DUO 4 K CCD diffractometer using an exposure time of 10 s/frame. A total of 3975 frames were collected with a frame width of 0.5° covering up to θ = 28.39° with 99.8% completeness accomplished.

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.
