Materials Data on H4C(N2O)2 by Materials Project

Abstract

CH4(N2O)2 crystallizes in the orthorhombic Fdd2 space group. The structure is zero-dimensional and consists of sixteen 2-nitroguanidine molecules. C4+ is bonded in a trigonal planar geometry to three N1- atoms. There is two shorter (1.33 Å) and one longer (1.37 Å) C–N bond length. There are four inequivalent N1- sites. In the first N1- site, N1- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the second N1- site, N1- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the third N1- site, N1- is bonded in a distorted bent 120 degrees geometry to one C4+ and one N1- atom. The N–N bond length is 1.34 Å. In the fourth N1- site, N1- is bonded in a distorted trigonal planar geometry to one N1- and two O2- atoms. There is one shorter (1.26 Å) and one longer (1.27 Å) N–O bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N1- atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N1- atom.
