Li2Sn(OF3)2 crystallizes in the monoclinic C2/m space group. Li(1) is bonded to two equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms to form LiO2F4 octahedra that share corners with four equivalent Sn(1)F6 octahedra and edges with two equivalent Li(1)O2F4 octahedra. The corner-sharing octahedral tilt angles range from 38-57°. Sn(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form SnF6 octahedra that share corners with eight equivalent Li(1)O2F4 octahedra. The corner-sharing octahedral tilt angles range from 38-57°. O(1) is bonded in a water-like geometry to two equivalent Li(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to one Li(1) and one Sn(1) atom. In the second F site, F(2) is bonded in a trigonal planar geometry to two equivalent Li(1) and one Sn(1) atom.
