The crystal structure of the title compound has been determined by single-crystal x-ray diffraction at 295 K and refined by least squares to a residual of 0.036 for 7 290 'observed' reflections.Crystals are triclinic, space group P<*>, with a = 14.493(8), b = 11.315(4), c = 11.745(4) Angstroem, α = 69.99(3), β = 84.67(4), γ = 62.27(3) deg, and Z = 2.The ruthenium environment is pseudo-tetrahedral, Ru-Cl 2.453(2), Ru-P 2.337(1), 2.335(1), 2.20₇ Angstroem.The phenyl ring environments are highly crowded and the nature of the steric interactions between them is examined.The structure of the trimethylphosphine analogue has also been determined, 1 805 'observed' reflections being refined to a residual of 0.059.Crystals are orthorombic, space group Pbca, with a = 29.251(8), b = 14.703(4), c = 14.649(7) Angstroem, and Z = 16.The two ruthenium enviroments are similar to that of the triphenylphosphine analogue.The Ru-Cl distances are 2.451(6), 2.440(5), and Ru-P 2.273(5)-2.280(6) Angstroem.The value of is 2.20 Angstroem.The syntheses and properties of and of the cationic derivatives ⁺ (L = MeCN, CO, CNBu^t, or PMe3) are also described.
