The crystal structure described by La3Tl is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. La(1) is bonded to eight equivalent La(1) and four equivalent Tl(1) atoms to form distorted LaLa8Tl4 cuboctahedra that share corners with twelve equivalent La(1)La8Tl4 cuboctahedra, edges with eight equivalent Tl(1)La12 cuboctahedra, edges with sixteen equivalent La(1)La8Tl4 cuboctahedra, faces with four equivalent Tl(1)La12 cuboctahedra, and faces with fourteen equivalent La(1)La8Tl4 cuboctahedra. Tl(1) is bonded to twelve equivalent La(1) atoms to form TlLa12 cuboctahedra that share corners with twelve equivalent Tl(1)La12 cuboctahedra, edges with twenty-four equivalent La(1)La8Tl4 cuboctahedra, faces with six equivalent Tl(1)La12 cuboctahedra, and faces with twelve equivalent La(1)La8Tl4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
