Serrano 113, 28006 Madrid, Spain and Laboratorio de Rayos X, Facultad de Ciencias Quimicas, Universidad Complutense, Ciudad Universitaria, 28040 Madrid, SpainThe compounds {Ru2(μ-O2CCH3)4[OP(p-RC6H4)3]2}PF6 (R = H, F, CH3O,Cl) containing the Ru25+ unit have been prepared by the reaction of Ru2Cl(μ-O2CCH3)4 and P(p-RC6H4)3 (R = H, F, CH3O, Cl) in the presence of NOPF6 in methanol. In all cases the oxidation of triarylphosphine to triarylphosphine oxide is observed and the Ru2(μ-O2CCH3)4+ unit remains unaltered. The X-ray structure of [Ru2(μ-O2CCH3)4(OPPh3)2]PF6 & CH2ClCH2Cl this compound crystallizes in the space group P<img class="imgLazyJSB inlineImage" height="15" width="11" alt="Full-size image (<1 K)" style="margin-top: -5 vertical-align: middle" title="Full-size image (<img height="15" border="0" style="vertical-align:bottom" width="11" alt="Full-size image (<1 K)" title="Full-size image (, with a = 8.46(2), b = 12.399(2), c = 13.017(4) &A, α = 105.18(2), β = 92.64(5), λ = 108.81(5)&, V = 1234(3) &A3. There are two half ruthenium dimers, one anion and an uncoordinated solvent CH2ClCH2Cl molecule per unit cell. Final R = 0.07 for 6591 observed reflections.
