Materials Data on KGeNO by Materials Project

Abstract

KGeNO crystallizes in the orthorhombic Pca2_1 space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to one N3- and five equivalent O2- atoms. The K–N bond length is 2.87 Å. There are a spread of K–O bond distances ranging from 2.70–3.04 Å. Ge4+ is bonded to three equivalent N3- and one O2- atom to form corner-sharing GeN3O tetrahedra. There is one shorter (1.88 Å) and two longer (1.89 Å) Ge–N bond length. The Ge–O bond length is 1.76 Å. N3- is bonded to one K1+ and three equivalent Ge4+ atoms to form distorted corner-sharing NKGe3 trigonal pyramids. O2- is bonded in a 1-coordinate geometry to five equivalent K1+ and one Ge4+ atom.
