Abstract: The title compound, [Hg₃(C₂₀H₁₆N₅)₄](NO₃)₂·4CH₃OH, consists of a trinuclear Hg^II dipositive cation, [Hg₃(4'-MeL)₄]²⁺, two nitrate anions and four occluded methanol molecules. The Hg atoms of the cation lie on a crystallographic twofold axis and are tetrahedrally coordinated by nitrogen-donor atoms of the bridging 1,3-bis(4-methyl-2-pyridylimino)isoindoline ligands. The central Hg atom is coordinated by four pyridine N atoms, one from each of the 4'-MeL^- ligands, while the two outer Hg atoms are each coordinated by two pyridine and two pyrrole N atoms.
