The material described by HgCl2 is Cyanogen Chloride-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four mercuric chloride molecules. Hg(1) is bonded in a linear geometry to one Cl(1) and one Cl(2) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a single-bond geometry to one Hg(1) atom. In the second Cl site, Cl(1) is bonded in a single-bond geometry to one Hg(1) atom. is represented by the CIF card [CIF]
