Materials Data on RbAgO by Materials Project

Abstract

RbAgO is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Rb1+ is bonded to six equivalent Ag1+ and four equivalent O2- atoms to form distorted RbAg6O4 tetrahedra that share corners with four equivalent AgRb6O4 tetrahedra, corners with six equivalent RbAg6O4 tetrahedra, edges with six equivalent AgRb6O4 tetrahedra, and faces with twelve equivalent RbAg6O4 tetrahedra. All Rb–Ag bond lengths are 3.19 Å. All Rb–O bond lengths are 2.76 Å. Ag1+ is bonded to six equivalent Rb1+ and four equivalent O2- atoms to form distorted AgRb6O4 tetrahedra that share corners with four equivalent RbAg6O4 tetrahedra, corners with six equivalent AgRb6O4 tetrahedra, edges with six equivalent RbAg6O4 tetrahedra, and faces with twelve equivalent AgRb6O4 tetrahedra. All Ag–O bond lengths are 2.76 Å. O2- is bonded in a body-centered cubic geometry to four equivalent Rb1+ and four equivalent Ag1+ atoms.
