In the title compound, [Hg(C42H38N4O2)](PF6)2·2CH3CN, the HgII cation lies on a twofold axis which is also the internal symmetry element of the complete cationic complex. The HgII cation is coordinated by two symmetry-related C(carbene) atoms [Hg—C = 2.058 (9) Å] in a nearly linear geometry, with a C—Hg—C angle of 175.8 (5)°. There are weak intermolecular C—HF interactions in the crystal packing between an F atom of a hexafluoridophosphate anion and a –CH2– group of the bis-N-heterocyclic carbene ligand.
