The compound described by CH3I is Ammonia-derived structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three iodomethane molecules. C(1) is bonded in a trigonal non-coplanar geometry to three equivalent H(1) and one I(1) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. I(1) is bonded in a single-bond geometry to one C(1) atom. is represented by the CIF card [CIF]
