Sn2OF5 crystallizes in the monoclinic C2/m space group. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a body-centered cubic geometry to two equivalent F(1), two equivalent F(3), and four equivalent F(4) atoms. In the second Sn site, Sn(2) is bonded to two equivalent O(1), two equivalent F(2), and two equivalent F(3) atoms to form corner-sharing SnO2F4 octahedra. The corner-sharing octahedral tilt angles range from 40-51°. In the third Sn site, Sn(3) is bonded to two equivalent O(1), one F(1), one F(2), and two equivalent F(4) atoms to form a mixture of corner and edge-sharing SnO2F4 octahedra. The corner-sharing octahedral tilt angles range from 40-51°. O(1) is bonded in a trigonal planar geometry to one Sn(2) and two equivalent Sn(3) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted linear geometry to one Sn(1) and one Sn(3) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Sn(2) and one Sn(3) atom. In the third F site, F(3) is bonded in a distorted single-bond geometry to one Sn(1) and one Sn(2) atom. In the fourth F site, F(4) is bonded in a bent 150 degrees geometry to one Sn(1) and one Sn(3) atom.
