The material structure described by (HgCl2)2Hg2SI2 is Cyanogen Chloride-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four mercuric chloride molecules and two Hg2SI2 clusters. In each Hg2SI2 cluster, Hg(2) is bonded in a linear geometry to one S(1) and one I(1) atom. S(1) is bonded in a linear geometry to two equivalent Hg(2) atoms. I(1) is bonded in a single-bond geometry to one Hg(2) atom. is represented by the CIF file [CIF]
