Materials Data on Na2GaAgBr6 by Materials Project
(Na)2AgGaBr6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight sodium molecules and one AgGaBr6 framework. In the AgGaBr6 framework, Ag1+ is bonded to six equivalent Br1- atoms to form AgBr6 octahedra that share corners with six equivalent GaBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ag–Br bond lengths are 2.79 Å. Ga3+ is bonded to six equivalent Br1- atoms to form GaBr6 octahedra that share corners with six equivalent AgBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ga–Br bond lengths are 2.57 Å. Br1- is bonded in a linear geometry to one Ag1+ and one Ga3+ atom.
