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 at om is in a pseudooctahedral coordination environment with two chelating dpp e ligands and one chelating acetate ligand. Intra-phosphine and intra-aceta te bond lengths and angles are unexceptional. Deviations from idealized oct ahedral 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 chel ate 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 tra ns to the acetate ligand [2.3074 (6) Angstrom]. The Ru1, C1 and C2 atoms li e on a twofold axis, and atom P3 of the anion lies on an inversion centre.
