Materials Data on Cs2GaAuF6 by Materials Project
Cs2AuGaF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent F1- atoms to form CsF12 cuboctahedra that share corners with twelve equivalent CsF12 cuboctahedra, faces with six equivalent CsF12 cuboctahedra, faces with four equivalent AuF6 octahedra, and faces with four equivalent GaF6 octahedra. All Cs–F bond lengths are 3.21 Å. Au1+ is bonded to six equivalent F1- atoms to form AuF6 octahedra that share corners with six equivalent GaF6 octahedra and faces with eight equivalent CsF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Au–F bond lengths are 2.57 Å. Ga3+ is bonded to six equivalent F1- atoms to form GaF6 octahedra that share corners with six equivalent AuF6 octahedra and faces with eight equivalent CsF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ga–F bond lengths are 1.94 Å. F1- is bonded in a 1-coordinate geometry to four equivalent Cs1+, one Au1+, and one Ga3+ atom.
