CuFAuF4 crystallizes in the triclinic P-1 space group. Au(1) is bonded in a square co-planar geometry to two equivalent F(2) and two equivalent F(3) atoms. Cu(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra are not tilted. There are three 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 bent 150 degrees geometry to one Au(1) and one Cu(1) atom. In the third F site, F(3) is bonded in a bent 120 degrees geometry to one Au(1) and one Cu(1) atom.
