Ga Ga Ge Rh
RhGa2Ge crystallizes in the monoclinic Pm space group. Rh(1) is bonded in a single-bond geometry to one Ga(1) and one Ge(1) atom. The Rh(1)-Ga(1) bond length is 2.73 Å. The Rh(1)-Ge(1) bond length is 0.53 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one Rh(1), one Ga(2), and four equivalent Ga(1) atoms to form a mixture of distorted edge and corner-sharing GaGa5Rh octahedra. The corner-sharing octahedra are not tilted. The Ga(1)-Ga(2) bond length is 2.40 Å. All Ga(1)-Ga(1) bond lengths are 2.90 Å. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to one Ga(1) and one Ge(1) atom. The Ga(2)-Ge(1) bond length is 2.20 Å. Ge(1) is bonded in a single-bond geometry to one Rh(1) and one Ga(2) atom.
