Sn3BrF5 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 3-coordinate geometry to one Br(1), one F(2), one F(3), and one F(4) atom. In the second Sn site, Sn(2) is bonded in a 3-coordinate geometry to one Br(1), one F(2), one F(3), and one F(5) atom. In the third Sn site, Sn(3) is bonded in a 4-coordinate geometry to one F(4), one F(5), and two equivalent F(1) atoms. Br(1) is bonded in a 2-coordinate geometry to one Sn(1) and one Sn(2) atom. There are five inequivalent F sites. In the first F site, F(5) is bonded in a bent 120 degrees geometry to one Sn(2) and one Sn(3) atom. In the second F site, F(1) is bonded in a 2-coordinate geometry to two equivalent Sn(3) atoms. In the third F site, F(2) is bonded in a bent 150 degrees geometry to one Sn(1) and one Sn(2) atom. In the fourth F site, F(3) is bonded in a bent 120 degrees geometry to one Sn(1) and one Sn(2) atom. In the fifth F site, F(4) is bonded in a bent 120 degrees geometry to one Sn(1) and one Sn(3) atom.
