CI2 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four tetraiodoethylene molecules. C(1) is bonded in a trigonal planar geometry to one C(1), one I(3), and one I(4) atom. There are two inequivalent I sites. In the first I site, I(3) is bonded in a single-bond geometry to one C(1) atom. In the second I site, I(4) is bonded in a single-bond geometry to one C(1) atom.
