CuSnF6 crystallizes in the triclinic P-1 space group. Cu(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form CuF6 octahedra that share corners with six equivalent Sn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 41-42°. Sn(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form SnF6 octahedra that share corners with six equivalent Cu(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 41-42°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to one Cu(1) and one Sn(1) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Cu(1) and one Sn(1) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Cu(1) and one Sn(1) atom.
