U3La is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. U(1) is bonded to eight equivalent U(1) and four equivalent La(1) atoms to form ULa4U8 cuboctahedra that share corners with twelve equivalent U(1)La4U8 cuboctahedra, edges with eight equivalent La(1)U12 cuboctahedra, edges with sixteen equivalent U(1)La4U8 cuboctahedra, faces with four equivalent La(1)U12 cuboctahedra, and faces with fourteen equivalent U(1)La4U8 cuboctahedra. La(1) is bonded to twelve equivalent U(1) atoms to form LaU12 cuboctahedra that share corners with twelve equivalent La(1)U12 cuboctahedra, edges with twenty-four equivalent U(1)La4U8 cuboctahedra, faces with six equivalent La(1)U12 cuboctahedra, and faces with twelve equivalent U(1)La4U8 cuboctahedra.
