RhBGe2 crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a 1-coordinate geometry to one B(1) and four equivalent Ge(1) atoms. The Rh(1)-B(1) bond length is 1.95 Å. There are a spread of Rh(1)-Ge(1) bond distances ranging from 2.57-2.86 Å. B(1) is bonded to one Rh(1) and four equivalent Ge(2) atoms to form a mixture of distorted corner and edge-sharing BGe4Rh square pyramids. There are a spread of B(1)-Ge(2) bond distances ranging from 1.87-2.25 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent Rh(1), one Ge(2), and four equivalent Ge(1) atoms. The Ge(1)-Ge(2) bond length is 3.05 Å. All Ge(1)-Ge(1) bond lengths are 2.91 Å. In the second Ge site, Ge(2) is bonded in a 4-coordinate geometry to four equivalent B(1) and one Ge(1) atom.
