Materials Data on CI4 by Materials Project
CI4 is Iron carbide-like structured and crystallizes in the tetragonal I-42m space group. The structure is zero-dimensional and consists of two periodomethane molecules. C4+ is bonded in a tetrahedral geometry to four equivalent I1- atoms. All C–I bond lengths are 2.18 Å. I1- is bonded in a single-bond geometry to one C4+ atom.
