The compound described by Sn2H2SO5F2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 5-coordinate geometry to one O(3), one O(5), one F(1), and two equivalent F(2) atoms. In the second Sn site, Sn(2) is bonded in a 4-coordinate geometry to one O(2), one O(4), one F(1), and one F(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(5) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(5) atom. S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(4) is bonded in a distorted single-bond geometry to one Sn(2) and one S(1) atom. In the second O site, O(5) is bonded in a distorted water-like geometry to one Sn(1), one H(1), and one H(2) atom. In the third O site, O(1) is bonded in a distorted single-bond geometry to one S(1) atom. In the fourth O site, O(2) is bonded in a 2-coordinate geometry to one Sn(2) and one S(1) atom. In the fifth O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Sn(1) and one S(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to one Sn(1) and one Sn(2) atom. In the second F site, F(2) is bonded in a distorted trigonal non-coplanar geometry to one Sn(2) and two equivalent Sn(1) atoms. is represented by the CIF file [CIF]
