The crystal structure described by Pm3La 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 La(1) atoms to form PmLa4Pm8 cuboctahedra that share corners with four equivalent La(1)Pm12 cuboctahedra, corners with fourteen equivalent Pm(1)La4Pm8 cuboctahedra, edges with six equivalent La(1)Pm12 cuboctahedra, edges with twelve equivalent Pm(1)La4Pm8 cuboctahedra, faces with four equivalent La(1)Pm12 cuboctahedra, and faces with sixteen equivalent Pm(1)La4Pm8 cuboctahedra. La(1) is bonded to twelve equivalent Pm(1) atoms to form LaPm12 cuboctahedra that share corners with six equivalent La(1)Pm12 cuboctahedra, corners with twelve equivalent Pm(1)La4Pm8 cuboctahedra, edges with eighteen equivalent Pm(1)La4Pm8 cuboctahedra, faces with eight equivalent La(1)Pm12 cuboctahedra, and faces with twelve equivalent Pm(1)La4Pm8 cuboctahedra. is represented by the CIF card [CIF]
