cis,cis,cis‐(Acetato‐O,O′)­bis­[1,2‐bis­(di­phenyl­phosphino)­ethane‐P,P′]­ruthenium(II) hexa­fluoro­phosphate di­methanol solvate

In the cation of the title complex, cis,cis,cis‐Ru(η²‐O₂CMe)(dppe)₂]PF₆·2MeOH dppe is 1,2‐bis­(di­phenyl­phosphino)­ethane, C₂₆H₂₄P₂], the Ru atom is in a pseudo‐octahedral coordination environment with two chelating dppe ligands and one chelating acetate ligand. Intra‐phosphine and intra‐acetate bond lengths and angles are unexceptional. Deviations from idealized octahedral coordination angles at ruthenium O—Ru—O 59.43 (8)° and P—Ru—P 103.19 (2)°] presumably derive from constraints imposed by the chelate rings. The Ru—P distances for the mutually trans P‐donor atoms 2.3785 (6) Å] are significantly longer than those for the Ru—P linkages trans to the acetate ligand 2.3074 (6) Å]. The Ru1, C1 and C2 atoms lie on a twofold axis, and atom P3 of the anion lies on an inversion centre.
