Dichlorido(g⁶-p-cymene)[tris(4-methoxyphenyl)phosphane]ruthenium(II)

The title compound, [RuCl₂(C₁₀H₁₄)(C₂₁H₂₁O₃P)], crystallizes with two complex molecules in the asymmetric unit. The Ru^II atom has a classical three-legged piano-stool environment being coordinated by a cymene ligand [Ru—centroid = 1.707 (2)/1.704 (2) A^̊ ], a tris(4-methoxyphenyl)phosphane ligand [Ru—P = 2.3629 (15)/2.3665 (15) A^̊ ] and two chloride atoms with the Ru—Cl bonds adopting two distinct values of 2.4068 (16)/2.4167 (16) and 2.4016 (15)/ 2.4244 (16) A^̊ . The effective cone and solid angles for the phosphane ligands were calculated to be 149.5/150.2^◦ and 25.3/25.6^◦, respectively. In the crystal, weak C—H∙ ∙ ∙Cl/O/π interactions are observed. The crystal was refined as a two-component twin.
