The material structure described by Pm3Pr is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded to eight equivalent Pm(1) and four equivalent Pr(1) atoms to form PmPm8Pr4 cuboctahedra that share corners with four equivalent Pr(1)Pm12 cuboctahedra, corners with fourteen equivalent Pm(1)Pm8Pr4 cuboctahedra, edges with six equivalent Pr(1)Pm12 cuboctahedra, edges with twelve equivalent Pm(1)Pm8Pr4 cuboctahedra, faces with four equivalent Pr(1)Pm12 cuboctahedra, and faces with sixteen equivalent Pm(1)Pm8Pr4 cuboctahedra. Pr(1) is bonded to twelve equivalent Pm(1) atoms to form PrPm12 cuboctahedra that share corners with six equivalent Pr(1)Pm12 cuboctahedra, corners with twelve equivalent Pm(1)Pm8Pr4 cuboctahedra, edges with eighteen equivalent Pm(1)Pm8Pr4 cuboctahedra, faces with eight equivalent Pr(1)Pm12 cuboctahedra, and faces with twelve equivalent Pm(1)Pm8Pr4 cuboctahedra. is represented by the CIF file [CIF]
