The complex Ru(1-3:5-6-η-C₈H₁₁)₂ (II) was prepared by the reduction of ruthenium trichloride hydrate with zinc in the presence of 1,5-cyclooctadiene at room temperature. Complex II, isomerized to Ru(η⁶-C₈H₁₀)(1-2:5-6-η-C₈H₁₂) (I) at 70°C by the migration of a hydrogen atom from one l-3:5-6-η-C₈H₁₁ ligand to the other. The ¹H and ¹³C NMR spectral evidence including selective irradiation studies suggests unsymmetrical coordination of the olefinic moiety of the 1-3:5-6-η-C₈H₁₁ ligand in the complex II.
