Materials Data on Na2AsAuF6 by Materials Project
(Na)2AuAsF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight sodium molecules and one AuAsF6 framework. In the AuAsF6 framework, Au1- is bonded to six equivalent F1- atoms to form AuF6 octahedra that share corners with six equivalent AsF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Au–F bond lengths are 2.42 Å. As5+ is bonded to six equivalent F1- atoms to form AsF6 octahedra that share corners with six equivalent AuF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All As–F bond lengths are 2.04 Å. F1- is bonded in a linear geometry to one Au1- and one As5+ atom.
