Description
Summary: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-H...N hydrogen bonds into a two-dimensional network parallel to (100).
