Lu5Pd2Sb crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to three equivalent Pd(1) and two equivalent Sb(1) atoms to form distorted LuSb2Pd3 trigonal bipyramids that share corners with four equivalent Lu(2)Sb2Pd4 octahedra, corners with twelve equivalent Lu(1)Sb2Pd3 trigonal bipyramids, edges with seven equivalent Lu(1)Sb2Pd3 trigonal bipyramids, faces with two equivalent Lu(2)Sb2Pd4 octahedra, and  a faceface with one Lu(1)Sb2Pd3 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 44-63°. In the second Lu site, Lu(2) is bonded to four equivalent Pd(1) and two equivalent Sb(1) atoms to form distorted LuSb2Pd4 octahedra that share corners with six equivalent Lu(2)Sb2Pd4 octahedra, corners with sixteen equivalent Lu(1)Sb2Pd3 trigonal bipyramids, and faces with eight equivalent Lu(1)Sb2Pd3 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 0-48°. Pd(1) is bonded in a 8-coordinate geometry to two equivalent Lu(2) and six equivalent Lu(1) atoms. Sb(1) is bonded in a 10-coordinate geometry to two equivalent Lu(2) and eight equivalent Lu(1) atoms.
