Crystal structure of aceto­nitrile­[η(6)-1-methyl-4-(1-methyl­eth­yl)benzene][1-(pyrimidin-2-yl)-3H-indol-1-ium-2-yl-κ(2) N,C]ruthenium(II) bis­(hexa­fluorido­anti­monate)

In the title compound, [Ru(C(10)H(14))(C(12)H(9)N(3))(CH(3)CN)][SbF(6)](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 aceto­nitrile solvent mol­ecule 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 SbF(6) (−) ions through weak C—H⋯F hydrogen bonds.
