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 [010], which are further linked into sheets parallel to (100) through C—HN hydrogen bonding interactions.

In the title complex, [HgI2(C21H19N5)2], the HgII ion is located on a twofold rotation axis and is coordinated by two I atoms and two N atoms from two (E)-2-{5,5-dimethyl-3-[4-(1H-1,2,4-triazol-1-yl)styryl]cyclohex-2-enylidene}malononitrile ligands in a distorted tetrahedral geometry. In the crystal, the molecules are linked by intermolecular π–π interactions between the triazole and benzene rings [centroid–centroid distance = 3.794 (3) Å] into a band extending in [010]. These bands are further connected by C—HN hydrogen bonds into a two-dimensional network parallel to (100).
