The compound described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
