The structure described by 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. is represented by the CIF file [CIF]
