Materials Data on Na2NbAgF6 by Materials Project
(Na)2AgNbF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight sodium molecules and one AgNbF6 framework. In the AgNbF6 framework, Nb3+ is bonded to six equivalent F1- atoms to form NbF6 octahedra that share corners with six equivalent AgF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Nb–F bond lengths are 2.07 Å. Ag1+ is bonded to six equivalent F1- atoms to form AgF6 octahedra that share corners with six equivalent NbF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ag–F bond lengths are 2.41 Å. F1- is bonded in a linear geometry to one Nb3+ and one Ag1+ atom.
