Lu5Pt2Sb crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to four equivalent Pt(1) and two equivalent Sb(1) atoms to form distorted corner-sharing LuSb2Pt4 octahedra. The corner-sharing octahedral tilt angles range from 0-47°. In the second Lu site, Lu(2) is bonded in a 5-coordinate geometry to three equivalent Pt(1) and two equivalent Sb(1) atoms. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Lu(1) and six equivalent Lu(2) atoms. Sb(1) is bonded in a 10-coordinate geometry to two equivalent Lu(1) and eight equivalent Lu(2) atoms.

In the first Lu site, Lu(1) is bonded to four equivalent Pt(1) and two equivalent Sb(1) atoms to form distorted corner-sharing LuSb2Pt4 octahedra. The corner-sharing octahedral tilt angles range from 0-47°. All Lu(1)-Pt(1) bond lengths are 2.90 Å. Both Lu(1)-Sb(1) bond lengths are 3.36 Å. In the second Lu site, Lu(2) is bonded in a 5-coordinate geometry to three equivalent Pt(1) and two equivalent Sb(1) atoms. There is one shorter (2.86 Å) and two longer (2.91 Å) Lu(2)-Pt(1) bond lengths. Both Lu(2)-Sb(1) bond lengths are 3.20 Å. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Lu(1) and six equivalent Lu(2) atoms. Sb(1) is bonded in a 10-coordinate geometry to two equivalent Lu(1) and eight equivalent Lu(2) atoms.
