Three ruthenocene derivatives: (⁵-4,7-dimethylindenyl)(⁵-pentamethylcyclopentadienyl)ruthenium(II), [⁵-[2](4,7)indeno[2]paracyclophanyl](⁵-pentamethylcyclopentadienyl)ruthenium(II) and bis[⁵-[2](4,7)indeno[2]paracyclophanyl]ruthenium(II)

Abstract: In the title compounds, [Ru(C₁₀H₁₅)(C₁₁H₁₁)], (III), [Ru(C₁₀H₁₅)(C₁₉H₁₇)], (IV), and [Ru(C₁₉H₁₇)₂], (V), respectively, the coordinating ring systems are planar and parallel, with the Ru atoms lying at perpendicular distances of Ru-Cp* 1.790 (1) Å and Ru-indenyl 1.836 (1) Å in (III), Ru-Cp* 1.791 (1) Å and Ru-indenyl 1.837 (1) Å in (IV), and Ru-indenyl 1.812 (1) Å and 1.809 (1) Å in (V) (Cp* is pentamethylcyclopentadienyl). The ring conformations are eclipsed for (III), staggered for (IV) and intermediate for (V). All three compounds show short intermolecular contacts from C-H groups to some ring centroids; these could be regarded as C-H [bold pi] hydrogen bonds. The molecules of each compound are thus connected via the 2₁ screw axis to form layers parallel to the xy plane.

Formula: [Ru(C₁₀H₁₅)(C₁₁H₁₁)], [Ru(C₁₀H₁₅)(C₁₉H₁₇)] and [Ru(C₁₉H₁₇)₂]
