The compound described by LuPd5Al2 crystallizes in the tetragonal I4/mmm space group. Lu(1) is bonded to four equivalent Pd(2) and eight equivalent Pd(1) atoms to form a mixture of face and corner-sharing LuPd12 cuboctahedra. There are two inequivalent Pd sites. In the first Pd site, Pd(2) is bonded in a distorted square co-planar geometry to four equivalent Lu(1) atoms. In the second Pd site, Pd(1) is bonded in a 6-coordinate geometry to two equivalent Lu(1) and four equivalent Al(1) atoms. Al(1) is bonded in a body-centered cubic geometry to eight equivalent Pd(1) atoms. is represented by the CIF file [CIF]
