The structure described by Th3Eu is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Th(1) is bonded to eight equivalent Th(1) and four equivalent Eu(1) atoms to form ThEu4Th8 cuboctahedra that share corners with twelve equivalent Th(1)Eu4Th8 cuboctahedra, edges with eight equivalent Eu(1)Th12 cuboctahedra, edges with sixteen equivalent Th(1)Eu4Th8 cuboctahedra, faces with four equivalent Eu(1)Th12 cuboctahedra, and faces with fourteen equivalent Th(1)Eu4Th8 cuboctahedra. Eu(1) is bonded to twelve equivalent Th(1) atoms to form EuTh12 cuboctahedra that share corners with twelve equivalent Eu(1)Th12 cuboctahedra, edges with twenty-four equivalent Th(1)Eu4Th8 cuboctahedra, faces with six equivalent Eu(1)Th12 cuboctahedra, and faces with twelve equivalent Th(1)Eu4Th8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
