PPh3Me[Os(NO)Cl4] is prepared by the reaction of (NO)2[Os(NO)Cl5] with methyltriphenylphosphonium chloride in CH2Cl2 solution. The complex forms brown, air stable crystals, which are characterized by the IR spectrum as well as by an X-ray structure determination (space group P1̄, two formula units per unit cell, a = 906, b = 1172, c = 1198 pm, α = 76.4, β = 84.8, γ = 82.4°, 3254 independent reflexions, Rw = 8.6%). The structure consists of [P(C6H5)3CH3]⊕ cations and disordered [Os-(NO)Cl4]⊖ anions; the latter have approximate C4V symmetry with a linearly coordinated nitrosyl ligand in the axial position.
