Materials Data on H6CN4O3 by Materials Project
N2CH2(NO)2H4O crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two nitrogen molecules, two CH2(NO)2 clusters, and two H4O clusters. In each CH2(NO)2 cluster, C4+ is bonded in a linear geometry to two N1- atoms. There is one shorter (1.17 Å) and one longer (1.37 Å) C–N bond length. There are two inequivalent N1- sites. In the first N1- site, N1- is bonded in a single-bond geometry to one C4+ atom. In the second N1- site, N1- is bonded in a trigonal non-coplanar geometry to one C4+ and two equivalent O2- atoms. Both N–O bond lengths are 1.43 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. O2- is bonded in a water-like geometry to one N1- and one H1+ atom. In each H4O cluster, there are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted single-bond geometry to one H1+ and one O2- atom. The H–H bond length is 0.92 Å. The H–O bond length is 1.17 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one H1+ atom. O2- is bonded in a bent 120 degrees geometry to two equivalent H1+ atoms.
