✦ Synopsis

The title compound, Hg~3~(C~20~H~16~N~5~)~4~~2~·4CH~3~OH, consists of a trinuclear Hg^II^ dipositive cation, [Hg~3~(4′-Me__L__)~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′-Me__L__
^−^ ligands, while the two outer Hg atoms are each coordinated by two pyridine and two pyrrole N atoms.

In the title compound, (C 4 H 12 N) 2 [Cu(C 3 S 5 ) 2 ], the Cu II atom lies on a centre of inversion and is coordinated by four S atoms from two 2-thioxo-1,3-dithiole-4,5-dithiolate ligands in a square-planar geometry.
