The material structure described by C3H8O2 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four dimethoxymethane molecules. There are three inequivalent C sites. In the first C site, C(2) is bonded to one H(4), one H(6), one H(7), and one O(2) atom to form corner-sharing CH3O tetrahedra. In the second C site, C(3) is bonded to one H(2), one H(5), one O(1), and one O(2) atom to form corner-sharing CH2O2 tetrahedra. In the third C site, C(1) is bonded to one H(1), one H(3), one H(8), and one O(1) atom to form corner-sharing CH3O tetrahedra. There are eight 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(3) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(4) is bonded in a single-bond geometry to one C(2) atom. In the fourth H site, H(6) is bonded in a single-bond geometry to one C(2) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one C(3) atom. In the sixth H site, H(2) is bonded in a single-bond geometry to one C(3) atom. In the seventh H site, H(7) is bonded in a single-bond geometry to one C(2) atom. In the eighth H site, H(8) is bonded in a single-bond geometry to one C(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one C(1) and one C(3) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one C(2) and one C(3) atom. is represented by the CIF file [CIF]
