The material described by Hg2NI is Cuprite-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure consists of four hydriodic acid atoms inside a Hg2N framework. In the Hg2N framework, there are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a linear geometry to two equivalent N(1) atoms. In the second Hg site, Hg(2) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to one Hg(1) and three equivalent Hg(2) atoms to form corner-sharing NHg4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
