Rh2ZnB crystallizes in the triclinic P1 space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 3-coordinate geometry to one Rh(2) and two equivalent B(1) atoms. The Rh(1)-Rh(2) bond length is 1.84 Å. There is one shorter (2.11 Å) and one longer (2.24 Å) Rh(1)-B(1) bond length. In the second Rh site, Rh(2) is bonded in a 3-coordinate geometry to one Rh(1) and two equivalent Zn(1) atoms. There is one shorter (2.61 Å) and one longer (2.71 Å) Rh(2)-Zn(1) bond length. Zn(1) is bonded in a 2-coordinate geometry to two equivalent Rh(2) and two equivalent B(1) atoms. There is one shorter (1.49 Å) and one longer (1.65 Å) Zn(1)-B(1) bond length. B(1) is bonded in a 4-coordinate geometry to two equivalent Rh(1) and two equivalent Zn(1) atoms.
