(1,6,7,12-Tetra­aza­perylene-κ(2) N,N′)bis­(4,4′,5,5′-tetra­methyl-2,2′-bipyridyl-κ(2) N,N′)ruthenium(II) bis­(hexa­fluorido­phosphate) aceto­nitrile tris­olvate

In the title compound, rac-[Ru(C(14)H(16)N(2))(2)(C(16)H(8)N(4))](PF(6))(2)·3C(2)H(3)N, discrete dimers of complex cations, [Ru(tmbpy)(2)­tape](2+), of opposite chirality are formed (tmbpy = tetra­methyl­bipyridine; tape = tetraazaperylene), held together by π–π stacking inter­actions between the tetra­aza­perylene moieties with centroid–centroid distances in the range 3.563 (3)–3.837 (3) Å. These inter­actions exhibit a parallel displaced π–π stacking mode. Additional weak C—H⋯π-ring and C—H⋯N and C—H⋯F inter­actions are found, leading to a three-dimensional architecture. The Ru(II) atom is coordinated in a distorted octa­hedral geometry. The counter-charge is provided by two hexa­fluorido­phosphate anions and the asymmetric unit is completed by three aceto­nitrile solvent mol­ecules of crystallization. Four F atoms of one PF(6) (−) anion are disordered over three sets of sites with occupancies of 0.517 (3):0.244 (3):0.239 (3). Two aceto­nitrile solvent mol­ecules are highly disordered and their estimated scattering contribution was subtracted from the observed diffraction data using the SQUEEZE option in PLATON [Spek (2009 ▶).
