The material structure described by Er3Pr is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Er(1) is bonded to eight equivalent Er(1) and four equivalent Pr(1) atoms to form ErPr4Er8 cuboctahedra that share corners with twelve equivalent Er(1)Pr4Er8 cuboctahedra, edges with eight equivalent Pr(1)Er12 cuboctahedra, edges with sixteen equivalent Er(1)Pr4Er8 cuboctahedra, faces with four equivalent Pr(1)Er12 cuboctahedra, and faces with fourteen equivalent Er(1)Pr4Er8 cuboctahedra. Pr(1) is bonded to twelve equivalent Er(1) atoms to form PrEr12 cuboctahedra that share corners with twelve equivalent Pr(1)Er12 cuboctahedra, edges with twenty-four equivalent Er(1)Pr4Er8 cuboctahedra, faces with six equivalent Pr(1)Er12 cuboctahedra, and faces with twelve equivalent Er(1)Pr4Er8 cuboctahedra. is represented by the CIF file [CIF]
