Abstract

In the title compound, [Ru(C10H14)(C12H9N3)(CH3CN)][SbF6]2, the ruthenium(II) cation is η (6)-coordinated by the para-cymene ligand with a Ru-centroid(η (6)-benzene) distance of 1.746 (2) Å. Furthermore, ruthenium coordinations to the C and N atoms of the pyrimidyl indole ligand are found to be 1.986 (4) and 2.082 (3) Å, respectively. The typical piano-stool coordination environment is saturated with an aceto-nitrile solvent mol-ecule with a Ru-N distance of 2.044 (3) Å. The indolyl ligand is protonated at the C3 position with the N=C imine bond length appropriate to that of related 3H-indole-based complexes. In the crystal, the complex cation is linked to the SbF6 (-) ions through weak C-H⋯F hydrogen bonds.
