(Cs2BrCl6)2F2 crystallizes in the cubic Fm-3m space group. The structure consists of four hydrofluoric acid atoms inside a Cs2BrCl6 framework. In the Cs2BrCl6 framework, Cs(1) is bonded to twelve equivalent Cl(1) atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent Cs(1)Cl12 cuboctahedra, faces with six equivalent Cs(1)Cl12 cuboctahedra, and faces with four equivalent Br(1)Cl6 octahedra. Br(1) is bonded to six equivalent Cl(1) atoms to form BrCl6 octahedra that share faces with eight equivalent Cs(1)Cl12 cuboctahedra. Cl(1) is bonded to four equivalent Cs(1) and one Br(1) atom to form a mixture of face, corner, and edge-sharing ClCs4Br square pyramids.
