The material described by Ho5Ir2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1) atoms. In the second Ho site, Ho(3) is bonded to four equivalent Ir(1) atoms to form distorted edge-sharing HoIr4 tetrahedra. In the third Ho site, Ho(2) 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 Ho(3), three equivalent Ho(1), and three equivalent Ho(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
