Pd3Tl is Uranium Silicide structured and crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to eight equivalent Pd(2) and four equivalent Tl(1) atoms to form distorted PdTl4Pd8 cuboctahedra that share corners with twelve equivalent Pd(1)Tl4Pd8 cuboctahedra, edges with eight equivalent Tl(1)Pd12 cuboctahedra, edges with sixteen equivalent Pd(2)Tl4Pd8 cuboctahedra, faces with four equivalent Tl(1)Pd12 cuboctahedra, faces with six equivalent Pd(1)Tl4Pd8 cuboctahedra, and faces with eight equivalent Pd(2)Tl4Pd8 cuboctahedra. In the second Pd site, Pd(2) is bonded to four equivalent Pd(1), four equivalent Pd(2), and four equivalent Tl(1) atoms to form distorted PdTl4Pd8 cuboctahedra that share corners with twelve equivalent Pd(2)Tl4Pd8 cuboctahedra, edges with eight equivalent Pd(1)Tl4Pd8 cuboctahedra, edges with eight equivalent Pd(2)Tl4Pd8 cuboctahedra, edges with eight equivalent Tl(1)Pd12 cuboctahedra, faces with four equivalent Pd(1)Tl4Pd8 cuboctahedra, faces with four equivalent Tl(1)Pd12 cuboctahedra, and faces with ten equivalent Pd(2)Tl4Pd8 cuboctahedra. Tl(1) is bonded to four equivalent Pd(1) and eight equivalent Pd(2) atoms to form TlPd12 cuboctahedra that share corners with twelve equivalent Tl(1)Pd12 cuboctahedra, edges with eight equivalent Pd(1)Tl4Pd8 cuboctahedra, edges with sixteen equivalent Pd(2)Tl4Pd8 cuboctahedra, faces with four equivalent Pd(1)Tl4Pd8 cuboctahedra, faces with six equivalent Tl(1)Pd12 cuboctahedra, and faces with eight equivalent Pd(2)Tl4Pd8 cuboctahedra.
