Pr3Ce is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pr(1) is bonded to eight equivalent Pr(1) and four equivalent Ce(1) atoms to form PrCe4Pr8 cuboctahedra that share corners with twelve equivalent Pr(1)Ce4Pr8 cuboctahedra, edges with eight equivalent Ce(1)Pr12 cuboctahedra, edges with sixteen equivalent Pr(1)Ce4Pr8 cuboctahedra, faces with four equivalent Ce(1)Pr12 cuboctahedra, and faces with fourteen equivalent Pr(1)Ce4Pr8 cuboctahedra. Ce(1) is bonded to twelve equivalent Pr(1) atoms to form CePr12 cuboctahedra that share corners with twelve equivalent Ce(1)Pr12 cuboctahedra, edges with twenty-four equivalent Pr(1)Ce4Pr8 cuboctahedra, faces with six equivalent Ce(1)Pr12 cuboctahedra, and faces with twelve equivalent Pr(1)Ce4Pr8 cuboctahedra.
