Di-μ-iodido-bis-{[(4-fluoro-benzoyl-methyl-ene)triphenyl-λ-phospho-rane]iodido-mercury(II)}.

In the title complex, [Hg(2)I(4)(C(26)H(20)FOP)(2)], the Hg(II) centre is four-coordinate with one short Hg-I bond [2.6895 (7) Å], one Hg-C bond and two asymmetric bridging Hg-I bonds with distances of 2.7780 (8) and 3.2599 (8) Å. The title mol-ecule has a crystallographic inversion centre at the centroid of the four-membered ring formed by the two Hg atoms and two I atoms. The crystal packing is stabilized by C-H⋯O hydrogen bonds.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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.
