Ce5Sn3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to two equivalent Sn(1) and four equivalent Sn(2) atoms to form corner-sharing CeSn6 octahedra. The corner-sharing octahedral tilt angles range from 0-52°. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to two equivalent Sn(1) and three equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted q6 geometry to two equivalent Ce(1) and eight equivalent Ce(2) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Ce(1), six equivalent Ce(2), and one Sn(2) atom.

In the first Ce site, Ce(1) is bonded to two equivalent Sn(1) and four equivalent Sn(2) atoms to form corner-sharing CeSn6 octahedra. The corner-sharing octahedral tilt angles range from 0-52°. Both Ce(1)-Sn(1) bond lengths are 3.41 Å. All Ce(1)-Sn(2) bond lengths are 3.28 Å. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to two equivalent Sn(1) and three equivalent Sn(2) atoms. Both Ce(2)-Sn(1) bond lengths are 3.34 Å. There is one shorter (3.16 Å) and two longer (3.31 Å) Ce(2)-Sn(2) bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted q6 geometry to two equivalent Ce(1) and eight equivalent Ce(2) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Ce(1), six equivalent Ce(2), and one Sn(2) atom. The Sn(2)-Sn(2) bond length is 3.01 Å.
