In the centrosymmetric dinuclear title compound, [Hg(2)Cl(4)(C(6)H(8)N(2))(2)], the Hg(II) ion is four-coordinated by one pyridine N atom from a 2-amino-4-methyl-pyridine ligand, one terminal Cl atom and two bridging Cl atoms. A distorted tetra-hedral geometry is formed around each Hg(II) ion. The crystal packing is stabilized by intra- and inter-molecular N-H⋯Cl hydrogen bonding. There are also π-π stacking inter-actions in the structure, with centroid-to-centroid distances of 3.594 (6) Å.
