PrCu2Sn2 crystallizes in the tetragonal P4/nmm space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Cu(1), four equivalent Cu(2), four equivalent Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Sn(2) atoms. In the second Cu site, Cu(2) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Sn(2), and four equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to four equivalent Pr(1) and four equivalent Cu(2) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Cu(2), and four equivalent Cu(1) atoms.
