In the title compound, [HgI2(C22H20N4)2], the HgII cation is situated on a twofold rotation axis and is coordinated by two iodide anions and two imidazolyl N atoms in a distorted tetrahedral geometry. In the crystal, C-HI interactions link the molecules into chains extending in , which are further linked into sheets parallel to (100) through C-HN hydrogen bonding interactions.
For the crystal structure of the organic ligand of the title compound, see: Zheng et al. (2013). For mercury(II) complexes in which the Hg(II) cation is four-coordinated by two terminal iodide ions and two N atoms from organic ligands in a distorted tetrahedral geometry, see: Li (2011); Shirvan et al. (2012).
