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.
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. All Pr(1)-Cu(1) bond lengths are 3.52 Å. There are two shorter (3.53 Å) and two longer (3.58 Å) Pr(1)-Sn(2) bond lengths. There are four shorter (3.46 Å) and two longer (3.51 Å) Pr(1)-Sn(1) bond lengths. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Sn(1), and four equivalent Sn(2) atoms. The Cu(1)-Sn(1) bond length is 2.52 Å. There are two shorter (2.63 Å) and two longer (2.73 Å) Cu(1)-Sn(2) bond lengths. 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. Both Sn(1)-Sn(1) bond lengths are 2.80 Å. 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.
