The material structure described by Rh2B is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent B(1) atoms. In the second Rh site, Rh(2) is bonded in a 4-coordinate geometry to four equivalent B(1) atoms. B(1) is bonded in a 7-coordinate geometry to three equivalent Rh(1) and four equivalent Rh(2) atoms. is represented by the CIF card [CIF]
