Cu3AsF12 is alpha Rhenium trioxide-derived structured and crystallizes in the cubic Im-3m space group. Cu(1) is bonded to two equivalent F(2) and four F(1,1,1) atoms to form CuF6 octahedra that share corners with two equivalent As(1)F6 octahedra and corners with four equivalent Cu(1)F6 octahedra. The corner-sharing octahedra are not tilted. As(1) is bonded to six equivalent F(2) atoms to form AsF6 octahedra that share corners with six equivalent Cu(1)F6 octahedra. The corner-sharing octahedra are not tilted. There are eleven inequivalent F sites. In the first F site, F(1) is bonded in a linear geometry to two equivalent Cu(1) atoms. In the second F site, F(2) is bonded in a linear geometry to one Cu(1) and one As(1) atom. In the third F site, F(1) is bonded in a linear geometry to two equivalent Cu(1) atoms. In the fourth F site, F(1) is bonded in a linear geometry to two equivalent Cu(1) atoms. In the fifth F site, F(1) is bonded in a linear geometry to two equivalent Cu(1) atoms. In the sixth F site, F(2) is bonded in a linear geometry to one Cu(1) and one As(1) atom. In the seventh F site, F(2) is bonded in a linear geometry to one Cu(1) and one As(1) atom. In the eighth F site, F(2) is bonded in a linear geometry to one Cu(1) and one As(1) atom. In the ninth F site, F(2) is bonded in a linear geometry to one Cu(1) and one As(1) atom. In the tenth F site, F(1) is bonded in a linear geometry to two equivalent Cu(1) atoms. In the eleventh F site, F(1) is bonded in a linear geometry to two equivalent Cu(1) atoms.
