Abstract: The asymmetric unit of the title compound, [Hg2Br4(C12H12N2)2], contains one half-molecule. The HgII atom is five-coordinated in a trigonal-bipyramidal configuration by two N atoms from the chelating 4,4'-dimethyl-2,2'-bipyridine ligand, two bridging Br and one terminal Br atom, leading to a centrosymmetric dimeric molecule. There is a [pi]-[pi] contact between the pyridine rings [centroid-to-centroid distance = 3.756 (5) Å].
