Bis[1,3-bis-(2-cyano-phen-yl)triazenido]mercury(II).

In the title compound, [Hg(C(14)H(8)N(5))(2)], the central atom is four-coordinated by two bidentate 1,3-bis-(2-cyano-phen-yl)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 mol-ecules of the complex are linked into pairs through non-classical C-H⋯N hydrogen bonds. The resulting dimeric units are assembled by translation along the crystallographic c axis into chains linked through secondary π-π inter-actions [centroid-centroid distances = 3.685 (2) and 3.574 (2) Å], as well as C-H⋯π stacking inter-actions, resulting in a two-dimensional architecture.
