Abstract
In the centrosymmetric dinuclear title compound, [Hg2Cl4(C6H8N2)2], the HgII ion is four-coordinated by one pyridine N atom from a 2-amino-4-methylpyridine ligand, one terminal Cl atom and two bridging Cl atoms. A distorted tetrahedral geometry is formed around each HgII ion. The crystal packing is stabilized by intra- and intermolecular N—H⋯Cl hydrogen bonding. There are also π–π stacking interactions in the structure, with centroid-to-centroid distances of 3.594 (6) Å.
