Materials Data on H(CO)2 by Materials Project

Abstract

H(CO)2 crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of four methanol with formaldehyde molecules. there are two inequivalent C+2.50+ sites. In the first C+2.50+ site, C+2.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.29 Å. In the second C+2.50+ site, C+2.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.25 Å. H1- is bonded in a linear geometry to two O2- atoms. There is one shorter (1.07 Å) and one longer (1.43 Å) H–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one C+2.50+ and one H1- atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one C+2.50+ and one H1- atom.
