The crystal structure described by Er5Pd2Sb crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded to four equivalent Pd(1) and two equivalent Sb(1) atoms to form distorted ErSb2Pd4 octahedra that share corners with six equivalent Er(1)Sb2Pd4 octahedra, corners with sixteen equivalent Er(2)Sb2Pd3 trigonal bipyramids, and faces with eight equivalent Er(2)Sb2Pd3 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 0-49°. In the second Er site, Er(2) is bonded to three equivalent Pd(1) and two equivalent Sb(1) atoms to form distorted ErSb2Pd3 trigonal bipyramids that share corners with four equivalent Er(1)Sb2Pd4 octahedra, corners with twelve equivalent Er(2)Sb2Pd3 trigonal bipyramids, edges with seven equivalent Er(2)Sb2Pd3 trigonal bipyramids, faces with two equivalent Er(1)Sb2Pd4 octahedra, and  a faceface with one Er(2)Sb2Pd3 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 44-63°. Pd(1) is bonded in a 8-coordinate geometry to two equivalent Er(1) and six equivalent Er(2) atoms. Sb(1) is bonded in a 10-coordinate geometry to two equivalent Er(1) and eight equivalent Er(2) atoms. is represented by the CIF file [CIF]
