Abstract: The title compound, [Ru(C10H15)(NO)(HOCH2CH2OH)](CF3SO3)2, possesses a three-legged piano-stool geometry around the Ru atom, with an average Ru-O distance of 2.120 (6) Å and an Ru-N-O angle of 159.45 (14)°. The ethyleneglycol ligand forms a non-planar metallacyclic ring by chelating the Ru atom via the O atoms. The OO distances of 2.554 (2) and 2.568 (2) Å are indicative of hydrogen bonding between coordinated ethyleneglycol and outer-sphere trifluoromethanesulfonate fragments. The crystal packing is stabilized by ionic forces and several CH3·F (2.585 and 2.640 Å) and CH3O interactions (2.391, 2.678, 2.694 and 2.699 Å) between the pentamethylcyclopentadienyl ligand and trifluoromethanesulfonate anion. There is noticeable short intermolecular contact [2.9039 (16) Å], between an O atom of the SO3 group and a C atom of the pentamethylcyclopentadienyl ligand.
