In the molecule of the title compound, [HgI2(C12H12N2)], the HgII atom is four-coordinated in a distorted tetrahedral configuration by two N atoms from 5,5'-dimethyl-2,2'-bipyridine and two I atoms. There is a [pi]-[pi] contact between pyridine rings of adjacent molecules [centroid-centroid distance = 3.723 (5) Å].
