YPd5Al2 crystallizes in the tetragonal I4/mmm space group. Y(1) is bonded to four equivalent Pd(1) and eight equivalent Pd(2) atoms to form a mixture of corner and face-sharing YPd12 cuboctahedra. There are two 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 in a 6-coordinate geometry to two equivalent Y(1) and four equivalent Al(1) atoms. Al(1) is bonded in a body-centered cubic geometry to eight equivalent Pd(2) atoms.
YPd5Al2 crystallizes in the tetragonal I4/mmm space group. Y(1) is bonded to four equivalent Pd(1) and eight equivalent Pd(2) atoms to form a mixture of corner and face-sharing YPd12 cuboctahedra. All Y(1)-Pd(1) bond lengths are 2.91 Å. All Y(1)-Pd(2) bond lengths are 2.98 Å. There are two 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 in a 6-coordinate geometry to two equivalent Y(1) and four equivalent Al(1) atoms. There are two shorter (2.55 Å) and two longer (2.61 Å) Pd(2)-Al(1) bond lengths. Al(1) is bonded in a body-centered cubic geometry to eight equivalent Pd(2) atoms.
