YSn3 crystallizes in the tetragonal I4/mmm space group. Y(1) is bonded to four equivalent Sn(1) and eight equivalent Sn(2) atoms to form a mixture of face, corner, and edge-sharing YSn12 cuboctahedra. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a square co-planar geometry to four equivalent Y(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Y(1) and four equivalent Sn(2) atoms.
