The structure described by CH3I is Ammonia-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four iodomethane molecules. C(1) is bonded in a trigonal non-coplanar geometry to one H(1), two equivalent H(2), and one I(1) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) 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]
