CrRhB2 crystallizes in the triclinic P1 space group. Cr(1) is bonded in a 5-coordinate geometry to two equivalent Rh(1), one B(1), and two equivalent B(2) atoms. There is one shorter (1.70 Å) and one longer (2.32 Å) Cr(1)-Rh(1) bond length. The Cr(1)-B(1) bond length is 2.19 Å. There is one shorter (1.70 Å) and one longer (2.32 Å) Cr(1)-B(2) bond length. Rh(1) is bonded in a 2-coordinate geometry to two equivalent Cr(1) and two equivalent B(1) atoms. There is one shorter (1.69 Å) and one longer (2.32 Å) Rh(1)-B(1) bond length. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 4-coordinate geometry to one Cr(1), two equivalent Rh(1), and one B(2) atom. The B(1)-B(2) bond length is 1.69 Å. In the second B site, B(2) is bonded in a 1-coordinate geometry to two equivalent Cr(1) and one B(1) atom.
