PrSn2 is Zirconium Disilicide-like structured and crystallizes in the orthorhombic Cmmm space group. Pr(1) is bonded in a 10-coordinate geometry to two equivalent Sn(2), two equivalent Sn(3), and six equivalent Sn(1) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to six equivalent Pr(1) and two equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a distorted square co-planar geometry to four equivalent Pr(1) and four equivalent Sn(3) atoms. In the third Sn site, Sn(3) is bonded in a distorted square co-planar geometry to four equivalent Pr(1) and four equivalent Sn(2) atoms.
PrSn2 is Zirconium Disilicide-like structured and crystallizes in the orthorhombic Cmmm space group. Pr(1) is bonded in a 10-coordinate geometry to two equivalent Sn(2), two equivalent Sn(3), and six equivalent Sn(1) atoms. Both Pr(1)-Sn(2) bond lengths are 3.26 Å. Both Pr(1)-Sn(3) bond lengths are 3.30 Å. There are four shorter (3.31 Å) and two longer (3.60 Å) Pr(1)-Sn(1) bond lengths. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to six equivalent Pr(1) and two equivalent Sn(1) atoms. Both Sn(1)-Sn(1) bond lengths are 3.01 Å. In the second Sn site, Sn(2) is bonded in a distorted square co-planar geometry to four equivalent Pr(1) and four equivalent Sn(3) atoms. All Sn(2)-Sn(3) bond lengths are 3.22 Å. In the third Sn site, Sn(3) is bonded in a distorted square co-planar geometry to four equivalent Pr(1) and four equivalent Sn(2) atoms.
