The title compound, [Ru 2 (μ-O 2 CCH 3 ) 4 (C 5 H 4 ClN) 2 ]PF 6 ·C 2 H 4 Cl 2 , was obtained via a rapid substitution reaction of 3-chloro-pyridine for water in [Ru 2 (μ-O 2 CCH 3 ) 4 (H 2 O) 2 ]PF 6 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.
