In the title complex, [Hg₂I₄(C₂₆H₂₀FOP)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 molecule 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-HO hydrogen bonds.
