YSnF5 crystallizes in the orthorhombic Immm space group. Y(1) is bonded to two F(1,1); two equivalent F(2); and two equivalent F(3) atoms to form YF6 octahedra that share corners with two equivalent Y(1)F6 octahedra and corners with six equivalent Sn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 0-57°. Sn(1) is bonded to two equivalent F(2) and four F(1,1) atoms to form distorted SnF6 octahedra that share corners with six equivalent Y(1)F6 octahedra and edges with two equivalent Sn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 0-57°. There are five inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to one Y(1) and two equivalent Sn(1) atoms. In the second F site, F(1) is bonded in a trigonal planar geometry to one Y(1) and two equivalent Sn(1) atoms. In the third F site, F(2) is bonded in a linear geometry to one Y(1) and one Sn(1) atom. In the fourth F site, F(3) is bonded in a linear geometry to two equivalent Y(1) atoms. In the fifth F site, F(1) is bonded in a trigonal planar geometry to one Y(1) and two equivalent Sn(1) atoms.
