The crystal structure described by Rh5B4 crystallizes in the hexagonal P6_3/mmc space group. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 6-coordinate geometry to three equivalent B(1) and three equivalent B(2) atoms. In the second Rh site, Rh(2) is bonded in a distorted trigonal non-coplanar geometry to four equivalent B(1) atoms. In the third Rh site, Rh(3) is bonded in a 6-coordinate geometry to six equivalent B(2) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 8-coordinate geometry to three equivalent Rh(1), four equivalent Rh(2), and one B(2) atom. In the second B site, B(2) is bonded in a 8-coordinate geometry to three equivalent Rh(1), three equivalent Rh(3), one B(1), and one B(2) atom. is represented by the CIF file [CIF]
