Cs2TaF6Hg crystallizes in the cubic Fm-3m space group. The structure consists of four 7439-97-6 atoms inside a Cs2TaF6 framework. In the Cs2TaF6 framework, Cs(1) is bonded to twelve equivalent F(1) atoms to form distorted CsF12 cuboctahedra that share corners with twelve equivalent Cs(1)F12 cuboctahedra, faces with six equivalent Cs(1)F12 cuboctahedra, and faces with four equivalent Ta(1)F6 octahedra. Ta(1) is bonded to six equivalent F(1) atoms to form TaF6 octahedra that share faces with eight equivalent Cs(1)F12 cuboctahedra. F(1) is bonded in a single-bond geometry to four equivalent Cs(1) and one Ta(1) atom.
