Materials Data on Na2AgAuBr6 by Materials Project
(Na)2AuAgBr6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight sodium molecules and one AuAgBr6 framework. In the AuAgBr6 framework, Au3+ is bonded to six equivalent Br1- atoms to form AuBr6 octahedra that share corners with six equivalent AgBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Au–Br bond lengths are 2.67 Å. Ag1+ is bonded to six equivalent Br1- atoms to form AgBr6 octahedra that share corners with six equivalent AuBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ag–Br bond lengths are 2.71 Å. Br1- is bonded in a linear geometry to one Au3+ and one Ag1+ atom.
