B Rh Rh Cl
Rh2BCl crystallizes in the monoclinic Cm space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to four equivalent Rh(2) and one B(1) atom. There are a spread of Rh(1)-Rh(2) bond distances ranging from 2.02-2.38 Å. The Rh(1)-B(1) bond length is 0.43 Å. In the second Rh site, Rh(2) is bonded in a 10-coordinate geometry to four equivalent Rh(1), four equivalent B(1), and two equivalent Cl(1) atoms. There are a spread of Rh(2)-B(1) bond distances ranging from 2.00-2.36 Å. There is one shorter (3.00 Å) and one longer (3.10 Å) Rh(2)-Cl(1) bond length. B(1) is bonded in a single-bond geometry to one Rh(1) and four equivalent Rh(2) atoms. Cl(1) is bonded in a linear geometry to two equivalent Rh(2) atoms.
