RhGe2Si crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a 13-coordinate geometry to four equivalent Rh(1), four equivalent Ge(1), four equivalent Ge(2), and one Si(1) atom. All Rh(1)-Rh(1) bond lengths are 2.97 Å. There are a spread of Rh(1)-Ge(1) bond distances ranging from 3.25-3.33 Å. There are a spread of Rh(1)-Ge(2) bond distances ranging from 3.25-3.33 Å. The Rh(1)-Si(1) bond length is 2.97 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 5-coordinate geometry to four equivalent Rh(1), one Ge(2), and four equivalent Si(1) atoms. The Ge(1)-Ge(2) bond length is 2.12 Å. There are a spread of Ge(1)-Si(1) bond distances ranging from 2.09-2.21 Å. In the second Ge site, Ge(2) is bonded in a 13-coordinate geometry to four equivalent Rh(1), one Ge(1), four equivalent Ge(2), and four equivalent Si(1) atoms. All Ge(2)-Ge(2) bond lengths are 2.97 Å. There are a spread of Ge(2)-Si(1) bond distances ranging from 2.64-2.74 Å. Si(1) is bonded in a 4-coordinate geometry to one Rh(1), four equivalent Ge(1), and four equivalent Ge(2) atoms.
