The title compound, [Ru2(μ-O2CCH3)4(C5H4ClN)2]PF6·C2H4Cl2, was obtained via a rapid substitution reaction of 3-chloro-pyridine for water in [Ru2(μ-O2CCH3)4(H2O)2]PF6 in 2-propanol and subsequent crystallization from a di-chloro-ethane solution. The cationic diruthenium(II,III) tetra-acetate core lies on a crystallographic inversion center with Ru-Ru and Ru-N bond lengths of 2.2738 (3) and 2.2920 (17) Å, respectively. The Ru-Ru-N bond angle is close to linear at 176.48 (4)°, and a significant π-stacking inter-action of 3.5649 (16) Å is seen between overlapping pyridine rings of adjacent cations.The title compound, [Ru2(μ-O2CCH3)4(C5H4ClN)2]PF6·C2H4Cl2, was obtained via a rapid substitution reaction of 3-chloro-pyridine for water in [Ru2(μ-O2CCH3)4(H2O)2]PF6 in 2-propanol and subsequent crystallization from a di-chloro-ethane solution.
