The compound described by HgI2 is Cyanogen Chloride-derived structured and crystallizes in the orthorhombic Cmc2_1 space group. The structure is zero-dimensional and consists of four mercury diiodide molecules. Hg(1) is bonded in a linear geometry to one I(1) and one I(2) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded in a single-bond geometry to one Hg(1) atom. In the second I site, I(2) is bonded in a single-bond geometry to one Hg(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
