The material structure described by Hf3Ir5B2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 13-coordinate geometry to two equivalent Ir(2), eight equivalent Ir(1), and three equivalent B(1) atoms. In the second Hf site, Hf(2) is bonded in a body-centered cubic geometry to eight equivalent Ir(1) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to two equivalent Hf(2), four equivalent Hf(1), and two equivalent B(1) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to four equivalent Hf(1) and four equivalent B(1) atoms. B(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1), two equivalent Ir(2), and four equivalent Ir(1) atoms. is represented by the CIF file [CIF]
