Materials Data on H8C3O2 by Materials Project
C3H8O2 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+1.33- sites. In the first C+1.33- site, C+1.33- is bonded to three H1+ and one O2- atom to form corner-sharing CH3O tetrahedra. All C–H bond lengths are 1.10 Å. The C–O bond length is 1.43 Å. In the second C+1.33- site, C+1.33- is bonded to two H1+ and two O2- atoms to form corner-sharing CH2O2 tetrahedra. There is one shorter (1.10 Å) and one longer (1.11 Å) C–H bond length. Both C–O bond lengths are 1.42 Å. In the third C+1.33- site, C+1.33- is bonded to three H1+ and one O2- atom to form corner-sharing CH3O tetrahedra. All C–H bond lengths are 1.10 Å. The C–O bond length is 1.43 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C+1.33- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C+1.33- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C+1.33- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C+1.33- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C+1.33- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C+1.33- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one C+1.33- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one C+1.33- atom. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two C+1.33- atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two C+1.33- atoms.
