(η⁶-Benzene)­dichlorido­(chloro­dicyclo­hexyl­phosphane-κP)ruthenium(II) chloro­form monosolvate

The title compound, [RuCl₂(η⁶-C₆H₆)(C₁₂H₂₂ClP)]·CHCl₃, was prepared by reaction of [RuCl₂(η⁶-C₆H₆)]₂ with chloro­dicyclo­hexyl­phosphane in CHCl₃ at 323 K under argon. The Ru^II atom is surrounded by one arene ligand, two Cl atoms and a phosphane ligand in a piano-stool geometry. The phosphane ligand is linked by the P atom, with an Ru—P bond length of 2.3247 (4) Å. Both cyclo­hexyl rings at the P atom adopt a chair conformation. In the crystal, the Ru^II complex mol­ecule and the chloro­form solvent mol­ecule are linked by a bifurcated C—H...(Cl,Cl) hydrogen bond. Intra­molecular C—H...Cl hydrogen bonds are also observed.

(η⁶-Benzene)(carbonato-κ²O,O′)[di­cyclohex­yl(naphthalen-1-ylmeth­yl)phosphane-κP]ruthenium(II) chloro­form tris­olvate

The title compound, [Ru(CO₃)(η⁶-C₆H₆){(C₆H₁₁)₂P(CH₂C₁₀H₇)}]·3CHCl₃, was synthesized by carbonation of [RuCl₂(η⁶-C₆H₆){(C₆H₁₁)₂P(CH₂C₁₀H₇)}] with NaHCO₃ in methanol at room temperature. The Ru^II atom is surrounded by a benzene ligand, a chelating carbonate group and a phosphane ligand in a piano-stool configuration. The crystal packing is consolidated by C—H...O and C—H...Cl hydrogen-bonding inter­actions between adjacent metal complexes and between the complexes and the solvent mol­ecules. The asymmetric unit contains one metal complex and three chloro­form solvent mol­ecules of which only one was modelled. The estimated diffraction contributions of the other two strongly disordered chloro­form solvent mol­ecules were substracted from the observed diffraction data using the SQUEEZE procedure in PLATON [Spek (2009).
