Sc Si Si Rh
ScRhSi2 crystallizes in the triclinic P1 space group. Sc(1) is bonded in a bent 150 degrees geometry to one Si(1) and one Si(2) atom. The Sc(1)-Si(1) bond length is 0.20 Å. The Sc(1)-Si(2) bond length is 0.31 Å. Rh(1) is bonded to four equivalent Rh(1), one Si(1), and one Si(2) atom to form a mixture of corner and edge-sharing RhSi2Rh4 octahedra. The corner-sharing octahedra are not tilted. All Rh(1)-Rh(1) bond lengths are 2.94 Å. The Rh(1)-Si(1) bond length is 3.26 Å. The Rh(1)-Si(2) bond length is 3.26 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a single-bond geometry to one Sc(1) and one Rh(1) atom. In the second Si site, Si(2) is bonded in a single-bond geometry to one Sc(1) and one Rh(1) atom.
