CeCu2Sn2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce is bonded in a 12-coordinate geometry to eight Cu and eight Sn atoms. There are four shorter (3.36 Å) and four longer (3.44 Å) Ce–Cu bond lengths. There are four shorter (3.37 Å) and four longer (3.56 Å) Ce–Sn bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded in a 12-coordinate geometry to four equivalent Ce and four equivalent Sn atoms. All Cu–Sn bond lengths are 2.61 Å. In the second Cu site, Cu is bonded in a 9-coordinate geometry to four equivalent Ce and five Sn atoms. There are one shorter (2.52 Å) and four longer (2.65 Å) Cu–Sn bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometry to four equivalent Ce and four equivalent Cu atoms. In the second Sn site, Sn is bonded in a 9-coordinate geometry to four equivalent Ce and five Cu atoms.
