CuAsF7 crystallizes in the orthorhombic Imma space group. Cu(1) is bonded to two equivalent F(1) and four equivalent F(3) atoms to form CuF6 octahedra that share corners with two equivalent Cu(1)F6 octahedra and corners with four equivalent As(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 40-45°. As(1) is bonded to two equivalent F(2) and four equivalent F(3) atoms to form AsF6 octahedra that share corners with four equivalent Cu(1)F6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Cu(1) atoms. In the second F site, F(2) is bonded in a single-bond geometry to one As(1) atom. In the third F site, F(3) is bonded in a distorted bent 150 degrees geometry to one Cu(1) and one As(1) atom.
