The compound described by Y5Ir2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1) atoms. In the second Y site, Y(3) is bonded to four equivalent Ir(1) atoms to form distorted edge-sharing YIr4 tetrahedra. In the third Y site, Y(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 Y(3), three equivalent Y(1), and three equivalent Y(2) atoms. is represented by the CIF card [CIF]
