PrPb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pr is bonded to twelve equivalent Pb atoms to form a mixture of corner and face-sharing PrPb12 cuboctahedra. All Pr–Pb bond lengths are 3.51 Å. Pb is bonded in a distorted square co-planar geometry to four equivalent Pr atoms.
