The material structure described by Pr3Al 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 Al(1) atoms to form distorted PrPr8Al4 cuboctahedra that share corners with twelve equivalent Pr(1)Pr8Al4 cuboctahedra, edges with eight equivalent Al(1)Pr12 cuboctahedra, edges with sixteen equivalent Pr(1)Pr8Al4 cuboctahedra, faces with four equivalent Al(1)Pr12 cuboctahedra, and faces with fourteen equivalent Pr(1)Pr8Al4 cuboctahedra. Al(1) is bonded to twelve equivalent Pr(1) atoms to form AlPr12 cuboctahedra that share corners with twelve equivalent Al(1)Pr12 cuboctahedra, edges with twenty-four equivalent Pr(1)Pr8Al4 cuboctahedra, faces with six equivalent Al(1)Pr12 cuboctahedra, and faces with twelve equivalent Pr(1)Pr8Al4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
