Pr3Pb is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pr is bonded in a distorted square co-planar geometry to four equivalent Pb atoms. All Pr–Pb bond lengths are 3.57 Å. Pb is bonded to twelve equivalent Pr atoms to form a mixture of face and corner-sharing PbPr12 cuboctahedra.
Pr3PbC is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional and consists of one medicinal charcoal molecule and one Pr3Pb framework. In the Pr3Pb framework, Pr is bonded in a linear geometry to two equivalent Pb atoms. Both Pr–Pb bond lengths are 2.97 Å. Pb is bonded to six equivalent Pr atoms to form corner-sharing PbPr6 octahedra. The corner-sharing octahedral tilt angles are 0°.
