The title compound, [Ru2(CH3CO2) 4(C6H4N2)2]PF 6·C2H4Cl2, was obtained via a rapid substitution reaction in 2-propanol whereby 3-cyano-pyridine replaces the axial water molecules in the diaquatetra -μ- acetato-diruthenium(II,III) hexa-fluorido-phosphate starting material. The product rapidly precipated and crystals were grown from 1,2-dichloro-ethane. The 1,2-dichloro-ethane molecule of solvation exhibits disorder with two different orientations [occupancy ratio 0.51 (6):0.49 (6)]. All three parts, the cation, the anion and the disordered solvent molecule lie on crystallographic inversion centers. The Ru - Ru bond length of 2.2702 (6) Å fits nicely into the range seen for similar complexes and correlates well with the reduction potential of the complex and donor strength of the axial ligand, 3-cyano-pyridine, as postulated in a previous study [Vamvounis et al. (2000). Inorg. Chim. Acta, 305, 87-98]. The 3-cyano-pyridine ligands orient themselves in an anti configuration with respect to each other and the Ru - Ru - N angle [174.27 (7)°] is close to being linear.
