The material structure described by Lu5Ir2 is Zircon-derived structured and crystallizes in the monoclinic C2/c space group. There are three inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to four equivalent Ir(1) atoms to form distorted edge-sharing LuIr4 tetrahedra. In the second Lu site, Lu(2) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. In the third Lu site, Lu(3) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. Ir(1) is bonded in a 8-coordinate geometry to two equivalent Lu(1), three equivalent Lu(2), and three equivalent Lu(3) atoms. is represented by the CIF file [CIF]
