Abstract: The title compound, [Ru₂Cl₃(C₁₀H₁₄)₂]₂[Hg₂Cl₆], contains two [{Ru(C₁₀H₁₄)}₂( [mu] -Cl)₃]⁺ cations and one [Hg₂Cl₆]^2- anion. In the cation, two [Ru( [eta] ⁶-p-cymene)] fragments are linked by three bridging Cl atoms. The anion lies on a twofold rotation axis. The coordination geometry of ruthenium is pseudo-octahedral, while the coordination around mercury is highly distorted tetrahedral. The average Ru-Cl bond length is 2.435 Å. The average bridging and terminal Hg-Cl distances are 2.664 and 2.435 Å, respectively.
