ReRhB2 crystallizes in the trigonal R3m space group. Re(1) is bonded in a 10-coordinate geometry to four equivalent Rh(1), three equivalent B(1), and three equivalent B(2) atoms. There are three shorter (2.33 Å) and one longer (2.50 Å) Re(1)-Rh(1) bond length. All Re(1)-B(1) bond lengths are 2.26 Å. All Re(1)-B(2) bond lengths are 2.26 Å. Rh(1) is bonded in a single-bond geometry to four equivalent Re(1), one B(2), and three equivalent B(1) atoms. The Rh(1)-B(2) bond length is 0.99 Å. All Rh(1)-B(1) bond lengths are 2.26 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a distorted hexagonal planar geometry to three equivalent Re(1) and three equivalent Rh(1) atoms. In the second B site, B(2) is bonded in a single-bond geometry to three equivalent Re(1) and one Rh(1) atom.
