The crystal structure described by SmRh4B4 crystallizes in the tetragonal P4_2/nmc space group. Sm(1) is bonded in a 24-coordinate geometry to twelve equivalent Rh(1) and twelve equivalent B(1) atoms. Rh(1) is bonded in a 5-coordinate geometry to three equivalent Sm(1) and five equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Sm(1), five equivalent Rh(1), and one B(1) atom. is represented by the CIF file [CIF]
