The material described by Tb5Pt2Sb crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to four equivalent Pt(1) and two equivalent Sb(1) atoms to form distorted TbSb2Pt4 octahedra that share corners with six equivalent Tb(1)Sb2Pt4 octahedra, corners with sixteen equivalent Tb(2)Sb2Pt3 trigonal bipyramids, and faces with eight equivalent Tb(2)Sb2Pt3 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 0-49°. In the second Tb site, Tb(2) is bonded to three equivalent Pt(1) and two equivalent Sb(1) atoms to form distorted TbSb2Pt3 trigonal bipyramids that share corners with four equivalent Tb(1)Sb2Pt4 octahedra, corners with twelve equivalent Tb(2)Sb2Pt3 trigonal bipyramids, edges with seven equivalent Tb(2)Sb2Pt3 trigonal bipyramids, faces with two equivalent Tb(1)Sb2Pt4 octahedra, and  a faceface with one Tb(2)Sb2Pt3 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 42-62°. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Tb(1) and six equivalent Tb(2) atoms. Sb(1) is bonded in a distorted q6 geometry to two equivalent Tb(1) and eight equivalent Tb(2) atoms. is represented by the CIF card [CIF]
