The material described by PrCuSn2 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 14-coordinate geometry to four equivalent Cu(1), four equivalent Sn(2), and six equivalent Sn(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Cu(1), and two equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
