In the title compound, an RhI centre is coordinated by a H8-BINAP 5,5′,6,6′,7,7′,8,8′-octahydro-2,2′-bis(diphenylphosphanyl)-1,1′-binaphthyl ligand and by a bidentate η2,η2-coordinated cod (cycloocta-1,5-diene) ligand. The asymmetric unit contains one cation, one anion and cocrystallized pentane [occupancy 0.720 (4)], as well as methanol [2 × 0.280 (4) occupancy] molecules.

In the title compound, the 2-[tris(pyridin-2-yl)methyl]pyridinium ion, monoprotonated species of tetrakis(pyridin-2-yl)methane, forms an intramolecular N—H⋯N hydrogen bond between the pyridinium and one of the pyridine rings. The trans-bis(acetonitrile)tetrachlororuthenate(III) anions form an undulating sheet parallel to the ac plane by C—H⋯Cl hydrogen bonds.

In the 2,3-diruthenocenylcyclopropenone, both cyclopentadienyl (Cp) rings are planar and parallel with staggered and eclipsed conformation between the mutual orientations of rings in the two independent sandwiches of ruthenocenyl molecule. The two Cp rings bonded to the cyclopropenone ring has deviates slightly from the coplanarity with 5.44 (3) and 1.02 (3)°, respectively.
