The structure described by UYPd6 is Uranium Silicide-derived structured and crystallizes in the tetragonal P4/mmm space group. U(1) is bonded to four equivalent Pd(2) and eight equivalent Pd(3) atoms to form UPd12 cuboctahedra that share corners with four equivalent U(1)Pd12 cuboctahedra, corners with eight equivalent Y(1)Pd12 cuboctahedra, faces with two equivalent Y(1)Pd12 cuboctahedra, faces with four equivalent U(1)Pd12 cuboctahedra, and faces with four equivalent Pd(2)U4Pd8 cuboctahedra. Y(1) is bonded to four equivalent Pd(1) and eight equivalent Pd(3) atoms to form YPd12 cuboctahedra that share corners with four equivalent Y(1)Pd12 cuboctahedra, corners with eight equivalent U(1)Pd12 cuboctahedra, edges with eight equivalent Pd(2)U4Pd8 cuboctahedra, faces with two equivalent U(1)Pd12 cuboctahedra, and faces with four equivalent Y(1)Pd12 cuboctahedra. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted square co-planar geometry to four equivalent Y(1) atoms. In the second Pd site, Pd(2) is bonded to four equivalent U(1) and eight equivalent Pd(3) atoms to form distorted PdU4Pd8 cuboctahedra that share corners with four equivalent Pd(2)U4Pd8 cuboctahedra, edges with eight equivalent Y(1)Pd12 cuboctahedra, faces with four equivalent U(1)Pd12 cuboctahedra, and faces with four equivalent Pd(2)U4Pd8 cuboctahedra. In the third Pd site, Pd(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent U(1), two equivalent Y(1), and two equivalent Pd(2) atoms. is represented by the CIF file [CIF]
