The material structure described by Tb5Ir2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1) atoms. In the second Tb site, Tb(3) is bonded to four equivalent Ir(1) atoms to form distorted edge-sharing TbIr4 tetrahedra. In the third Tb site, Tb(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 Tb(3), three equivalent Tb(1), and three equivalent Tb(2) atoms. is represented by the CIF card [CIF]
