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 ethyl-eneglycol ligand forms a non-planar metallacyclic ring by chelating the Ru atom via the O atoms. The O⋯O distances of 2.554 (2) and 2.568 (2) Å are indicative of hydrogen bonding between coordinated ethyl-eneglycol and outer-sphere trifluoro-methane-sulfonate fragments. The crystal packing is stabilized by ionic forces and several CH3⋯·F (2.585 and 2.640 Å) and CH3⋯O inter-actions (2.391, 2.678, 2.694 and 2.699 Å) between the penta-methyl-cyclo-penta-dienyl ligand and trifluoro-methane- sulfonate anion. There is noticeable short inter-molecular contact [2.9039 (16) Å], between an O atom of the SO3 group and a C atom of the penta-methyl-cyclo-penta-dienyl ligand.
