The material described by Ce(IrB)4 is alpha Pu-derived structured and crystallizes in the tetragonal P4_2/n space group. Ce(1) is bonded in a 20-coordinate geometry to eight equivalent Ir(1) and twelve equivalent B(1) atoms. Ir(1) is bonded in a 4-coordinate geometry to two equivalent Ce(1) and four equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Ce(1), four equivalent Ir(1), and one B(1) atom. is represented by the CIF card [CIF]
