The material structure described by Pm3Hf is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pm(1) is bonded to eight equivalent Pm(1) and four equivalent Hf(1) atoms to form PmPm8Hf4 cuboctahedra that share corners with twelve equivalent Pm(1)Pm8Hf4 cuboctahedra, edges with eight equivalent Hf(1)Pm12 cuboctahedra, edges with sixteen equivalent Pm(1)Pm8Hf4 cuboctahedra, faces with four equivalent Hf(1)Pm12 cuboctahedra, and faces with fourteen equivalent Pm(1)Pm8Hf4 cuboctahedra. Hf(1) is bonded to twelve equivalent Pm(1) atoms to form HfPm12 cuboctahedra that share corners with twelve equivalent Hf(1)Pm12 cuboctahedra, edges with twenty-four equivalent Pm(1)Pm8Hf4 cuboctahedra, faces with six equivalent Hf(1)Pm12 cuboctahedra, and faces with twelve equivalent Pm(1)Pm8Hf4 cuboctahedra. is represented by the CIF card [CIF]
