Abstract: In the title compound, [Hg(C₁₄H₈N₅)₂], the central atom is four-coordinated by two bidentate 1,3-bis(2-cyanophenyl)triazenide ligands in a distorted square-planar geometry. The asymmteric unit is composed of one ligand molecule and one Hg^II ion, which is disordered over two sites, one lying on an inversion center and the other on a general position with site-occupancy factors of 0.2378 (7) and 0.3811 (7), respectively. The monomeric molecules of the complex are linked into pairs through non-classical C-HN hydrogen bonds. The resulting dimeric units are assembled by translation along the crystallographic c axis into chains linked through secondary - interactions [centroid-centroid distances = 3.685 (2) and 3.574 (2) Å], as well as C-H stacking interactions, resulting in a two-dimensional architecture.
