Bis{tri-μ-chloro-bis[(η6-p-cymene)ruthenium(II)]} di-μ-chloro-bis[dichloromercurate(II)

Abstract

The title compound, [Ru2Cl3(C10H14)2]2[Hg2Cl6], contains two [{Ru(C10H14)}2(μ-Cl)3]+ cations and one [Hg2Cl6]2− anion. In the cation, two [Ru(η6-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 A. The average bridging and terminal Hg—Cl distances are 2.664 and 2.435 A, respectively.
