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

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 Å. The average bridging and terminal Hg—Cl distances are 2.664 and 2.435 Å, respectively.

Special details

Experimental. The data collection covered over a hemisphere of reciprocal space by a combination of three sets of exposures; each set had a different φ angle (0, 88 and 180°) for the crystal and each exposure of 20 s covered 0.3° in ω. The crystal-to-detector distance was 4 cm and the detector swing a ngle was -35°. Coverage of the unique set is over 99% complete. Crystal decay was monitored by repeating fifty initial frames at the end of data collection and analysing the duplicate reflections, and was found to be negligible.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
