Sn3SbF9 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to two equivalent F(2) and two equivalent F(4) atoms. In the second Sn site, Sn(2) is bonded in a distorted rectangular see-saw-like geometry to one F(2), one F(3), one F(4), and one F(5) atom. Sb(1) is bonded in a distorted square pyramidal geometry to one F(1), two equivalent F(3), and two equivalent F(5) atoms. There are five inequivalent F sites. In the first F site, F(4) is bonded in a bent 120 degrees geometry to one Sn(1) and one Sn(2) atom. In the second F site, F(5) is bonded in a distorted linear geometry to one Sn(2) and one Sb(1) atom. In the third F site, F(1) is bonded in a single-bond geometry to one Sb(1) atom. In the fourth F site, F(2) is bonded in a bent 150 degrees geometry to one Sn(1) and one Sn(2) atom. In the fifth F site, F(3) is bonded in a bent 150 degrees geometry to one Sn(2) and one Sb(1) atom.
