Materials Data on RbGe2N3 by Materials Project

Abstract

RbGe2N3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten N3- atoms. There are a spread of Rb–N bond distances ranging from 2.82–3.24 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 1.79–1.94 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a 2-coordinate geometry to four equivalent Rb1+ and two equivalent Ge4+ atoms. In the second N3- site, N3- is bonded in a distorted trigonal planar geometry to three equivalent Rb1+ and three equivalent Ge4+ atoms.
