The material structure described by CH is Indium-like structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of four isobutylene molecules. There are three inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one C(2) and two equivalent C(3) atoms. In the second C site, C(2) is bonded in a distorted water-like geometry to one C(1) and two equivalent H(2) atoms. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(1) and one H(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(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. is represented by the CIF card [CIF]
