M. R. Siqueira, J. Ellena and R. A. Burrow

Abstract: In the centrosymmetric molecule of the title compound, [Hg(C₁₂H₁₀O₂P)₂(C₅H₅N)₂(C₁₂H₁₁O₂P)₂], the approximately octahedral Hg atom is coordinated by two each of phenylphosphinate, phosphinic acid and pyridine ligands. Each pair of phosphinic acid and phosphinate ligands features an intramolecular hydrogen bond, so forming an eight-membered ring.
