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(eta(2)O(2)CMe)(dppe)(2)]PF6. 2MeOH [dppe is 1,2-bis(diphenylphosphino)ethane, C26H24P2], the Ru atom is in a pseudooctahedral 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)degrees and P-Ru-P 103.19 (2)degrees] presumably derive from constraints imposed by the chelate rings. The Ru-P distances for the mutually trans P-donor atoms [2.3785 (6) Angstrom] are significantly longer than those for the Ru-P linkages trans to the acetate ligand [2.3074 (6) Angstrom]. The Ru1, C1 and C2 atoms lie on a twofold axis, and atom P3 of the anion lies on an inversion centre.
