The compound described by Tb(IrB)2 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Fddd space group. Tb(1) is bonded to four equivalent Ir(1) and four equivalent B(1) atoms to form distorted face-sharing TbB4Ir4 hexagonal bipyramids. Ir(1) is bonded in a 7-coordinate geometry to two equivalent Tb(1) and five equivalent B(1) atoms. B(1) is bonded in a 8-coordinate geometry to two equivalent Tb(1), five equivalent Ir(1), and one B(1) atom. is represented by the CIF file [CIF]
