The material structure described by HgI is Indium-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is zero-dimensional and consists of two HgI clusters. Hg(1) is bonded in a distorted linear geometry to one Hg(1) and one I(1) atom. I(1) is bonded in a single-bond geometry to one Hg(1) atom. is represented by the CIF card [CIF]
