SnF2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to one F(1), one F(2), one F(4), and two equivalent F(3) atoms to form distorted corner-sharing SnF5 square pyramids. In the second Sn site, Sn(2) is bonded in a 3-coordinate geometry to one F(1), one F(4), and two equivalent F(2) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 120 degrees geometry to one Sn(1) and one Sn(2) atom. In the second F site, F(2) is bonded in a 3-coordinate geometry to one Sn(1) and two equivalent Sn(2) atoms. In the third F site, F(3) is bonded in a bent 150 degrees geometry to two equivalent Sn(1) atoms. In the fourth F site, F(4) is bonded in a linear geometry to one Sn(1) and one Sn(2) atom.

In the first Sn site, Sn(1) is bonded to one F(1), one F(2), one F(4), and two equivalent F(3) atoms to form distorted corner-sharing SnF5 square pyramids. The Sn(1)-F(1) bond length is 2.29 Å. The Sn(1)-F(2) bond length is 2.44 Å. The Sn(1)-F(4) bond length is 2.21 Å. There is one shorter (2.07 Å) and one longer (2.35 Å) Sn(1)-F(3) bond length. In the second Sn site, Sn(2) is bonded in a 3-coordinate geometry to one F(1), one F(4), and two equivalent F(2) atoms. The Sn(2)-F(1) bond length is 2.18 Å. The Sn(2)-F(4) bond length is 2.12 Å. There is one shorter (2.11 Å) and one longer (2.60 Å) Sn(2)-F(2) bond length. There are four inequivalent F sites.
