The Materials Project

CH2O crystallizes in the tetragonal I4_1/a space group. The structure is one-dimensional and consists of four CH2O ribbons oriented in the (0, 0, 1) direction. C2+ is bonded to two H and two equivalent 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. There is one shorter (1.39 Å) and one longer (1.44 Å) C–O bond length. There are two inequivalent H sites. In the first H site, H is bonded in a single-bond geometry to one C2+ atom. In the second H site, H is bonded in a single-bond geometry to one C2+ atom. O2- is bonded in a bent 120 degrees geometry to two equivalent C2+ atoms.
