The material structure described by Sm3Pm is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Sm(1) is bonded to eight equivalent Sm(1) and four equivalent Pm(1) atoms to form SmPm4Sm8 cuboctahedra that share corners with twelve equivalent Sm(1)Pm4Sm8 cuboctahedra, edges with eight equivalent Pm(1)Sm12 cuboctahedra, edges with sixteen equivalent Sm(1)Pm4Sm8 cuboctahedra, faces with four equivalent Pm(1)Sm12 cuboctahedra, and faces with fourteen equivalent Sm(1)Pm4Sm8 cuboctahedra. Pm(1) is bonded to twelve equivalent Sm(1) atoms to form PmSm12 cuboctahedra that share corners with twelve equivalent Pm(1)Sm12 cuboctahedra, edges with twenty-four equivalent Sm(1)Pm4Sm8 cuboctahedra, faces with six equivalent Pm(1)Sm12 cuboctahedra, and faces with twelve equivalent Sm(1)Pm4Sm8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
