The crystal structure described by Tb(IrB)2 is alpha Pu-derived structured and crystallizes in the orthorhombic Fddd space group. Tb(1) is bonded in a 18-coordinate geometry to eight equivalent Ir(1) and ten equivalent B(1) atoms. Ir(1) is bonded in a 4-coordinate geometry to four equivalent Tb(1) and four equivalent B(1) atoms. B(1) is bonded in a 4-coordinate geometry to five equivalent Tb(1) and four equivalent Ir(1) atoms. is represented by the CIF file [CIF]
