The crystal structure described by Y5Pd2Sb crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to four equivalent Pd(1) and two equivalent Sb(1) atoms to form distorted YSb2Pd4 octahedra that share corners with six equivalent Y(1)Sb2Pd4 octahedra, corners with sixteen equivalent Y(2)Sb2Pd3 trigonal bipyramids, and faces with eight equivalent Y(2)Sb2Pd3 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 0-49°. In the second Y site, Y(2) is bonded to three equivalent Pd(1) and two equivalent Sb(1) atoms to form distorted YSb2Pd3 trigonal bipyramids that share corners with four equivalent Y(1)Sb2Pd4 octahedra, corners with twelve equivalent Y(2)Sb2Pd3 trigonal bipyramids, edges with seven equivalent Y(2)Sb2Pd3 trigonal bipyramids, faces with two equivalent Y(1)Sb2Pd4 octahedra, and  a faceface with one Y(2)Sb2Pd3 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 43-63°. Pd(1) is bonded in a 8-coordinate geometry to two equivalent Y(1) and six equivalent Y(2) atoms. Sb(1) is bonded in a 10-coordinate geometry to two equivalent Y(1) and eight equivalent Y(2) atoms. is represented by the CIF file [CIF]
