The compound described by ErPr3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Er(1) is bonded to twelve equivalent Pr(1) atoms to form ErPr12 cuboctahedra that share corners with twelve equivalent Er(1)Pr12 cuboctahedra, edges with twenty-four equivalent Pr(1)Pr8Er4 cuboctahedra, faces with six equivalent Er(1)Pr12 cuboctahedra, and faces with twelve equivalent Pr(1)Pr8Er4 cuboctahedra. Pr(1) is bonded to four equivalent Er(1) and eight equivalent Pr(1) atoms to form PrPr8Er4 cuboctahedra that share corners with twelve equivalent Pr(1)Pr8Er4 cuboctahedra, edges with eight equivalent Er(1)Pr12 cuboctahedra, edges with sixteen equivalent Pr(1)Pr8Er4 cuboctahedra, faces with four equivalent Er(1)Pr12 cuboctahedra, and faces with fourteen equivalent Pr(1)Pr8Er4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
