Abstract

Cs2NaGaF6 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded to twelve F1- atoms to form distorted CsF12 cuboctahedra that share corners with nine CsF12 cuboctahedra, corners with three equivalent GaF6 octahedra, faces with seven CsF12 cuboctahedra, faces with three equivalent GaF6 octahedra, and faces with four equivalent NaF6 octahedra. The corner-sharing octahedral tilt angles are 12°. There are a spread of Cs–F bond distances ranging from 3.18–3.40 Å. In the second Cs1+ site, Cs1+ is bonded to twelve F1- atoms to form distorted CsF12 cuboctahedra that share corners with nine CsF12 cuboctahedra, corners with three equivalent NaF6 octahedra, faces with seven CsF12 cuboctahedra, faces with three equivalent NaF6 octahedra, and faces with four GaF6 octahedra. The corner-sharing octahedral tilt angles are 2°. There are a spread of Cs–F bond distances ranging from 3.16–3.26 Å. Na1+ is bonded to six F1- atoms to form distorted NaF6 octahedra that share corners with three equivalent CsF12 cuboctahedra, corners with three equivalent GaF6 octahedra, faces with seven CsF12 cuboctahedra, and a faceface with one GaF6 octahedra.
