Pr5Sn3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 6-coordinate geometry to two equivalent Sn(2) and four equivalent Sn(1) atoms. In the second Pr site, Pr(2) is bonded in a 4-coordinate geometry to four equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to two equivalent Pr(2) and eight equivalent Pr(1) atoms. In the second Sn site, Sn(2) is bonded in a 10-coordinate geometry to eight equivalent Pr(1) and two equivalent Sn(2) atoms.
