Ba(1) is bonded in a 12-coordinate geometry to one F(1), one F(2), two equivalent F(3), two equivalent F(4), two equivalent F(5), two equivalent F(6), and two equivalent F(7) atoms. Zn(1) is bonded to one F(1), one F(2), one F(3), one F(5), one F(6), and one F(7) atom to form ZnF6 octahedra that share corners with three equivalent Sn(1)F6 octahedra and  an edgeedge with one Sn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 57-63°. Sn(1) is bonded to one F(1), one F(2), one F(3), one F(4), one F(5), and one F(6) atom to form SnF6 octahedra that share corners with three equivalent Zn(1)F6 octahedra and  an edgeedge with one Zn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 57-63°. There are seven inequivalent F sites. In the first F site, F(1) is bonded in a bent 120 degrees geometry to one Ba(1), one Zn(1), and one Sn(1) atom.
