Mercury nitride

In chemistry, mercury nitrides are chemical compounds that contain mercury cations and nitride anions. Binary mercury nitrides, e.g. Hg3N2, are not well characterized and are probably unstable in the condensed phase under ordinary conditions. A nitride of mercury has been reported in the form of [Hg2N](NO3). This reddish solid adopts a network structure consisting of NHg4 tetrahedra linked by nitrate ligands.
