Materials Data on NaGe2N3 by Materials Project
NaGe2N3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. Na1+ is bonded in a 5-coordinate geometry to five N3- atoms. There are a spread of Na–N bond distances ranging from 2.37–2.84 Å. Ge4+ is bonded to four N3- atoms to form corner-sharing GeN4 tetrahedra. There are a spread of Ge–N bond distances ranging from 1.81–1.90 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a 5-coordinate geometry to three equivalent Na1+ and two equivalent Ge4+ atoms. In the second N3- site, N3- is bonded to one Na1+ and three equivalent Ge4+ atoms to form corner-sharing NNaGe3 trigonal pyramids.
