Dichloro­tris(triphenyl­phosphine)ruthenium(II) dichloro­methane hemisolvate

A third modification of [RuCl₂(PPh₃)₃] has been characterized, this time as the title compound, [RuCl₂(C₁₈H₁₅P)₃]·0.5CH₂Cl₂. As seen for the previous modifications, the complex has a distorted square-pyramidal geometry with an ortho-H atom `blocking' the site trans to the apical PPh₃ ligand. There is no evidence for a strong C—H...Ru inter­action nor any specific directional force in the solid state.
