Materials Data on Ge2N2O by Materials Project

Abstract

Ge2N2O crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to three N3- and one O2- atom to form corner-sharing GeN3O tetrahedra. All Ge–N bond lengths are 1.87 Å. The Ge–O bond length is 1.78 Å. In the second Ge4+ site, Ge4+ is bonded to three N3- and one O2- atom to form corner-sharing GeN3O tetrahedra. There is two shorter (1.85 Å) and one longer (1.86 Å) Ge–N bond length. The Ge–O bond length is 1.80 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal non-coplanar geometry to three Ge4+ atoms. In the second N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to three Ge4+ atoms. O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms.
