The crystal structure described by PrPb2 is Zirconium Disilicide-like structured and crystallizes in the tetragonal I4_1/amd space group. Pr(1) is bonded in a 10-coordinate geometry to four equivalent Pb(1) and six equivalent Pb(2) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted square co-planar geometry to four equivalent Pr(1) atoms. In the second Pb site, Pb(2) is bonded in a 8-coordinate geometry to six equivalent Pr(1) and two equivalent Pb(2) atoms. is represented by the CIF card [CIF]
