The reaction of (I) with phenoxides yields the title compound, II.This represents a new synthesis of compound II.Crystals of II were obtained from hexane/toluene.II crystallizes in the monoclinic P2₁/c space group with a 15.39(1), b 15.33(1), c 27.16(1) Angstroem, β 94.32(5) deg, Z = 4, D_x 1.39 g/cm³.The structure was solved at ambient temperature using Mo-K_α radiation with μ 4.1 cm^-1, F(000) = 2767.70 and R = 0.0780, (R_w = 0.0718).There were 4991 unique observed reflections.The main feature of the structure is the presence of two orthometallated triphenylphosphite ligands and two conventional triphenylphosphite ligands leading to the presence of cis-aryl linkages about ruthenium.The mechanism of formation of II from I is discussed.
