Sc Cu Rh Rh
ScRh2Cu crystallizes in the monoclinic Cm space group. Sc(1) is bonded in a single-bond geometry to four equivalent Rh(1) and one Cu(1) atom. There are a spread of Sc(1)-Rh(1) bond distances ranging from 2.56-3.23 Å. The Sc(1)-Cu(1) bond length is 0.39 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to four equivalent Sc(1) and one Rh(2) atom. The Rh(1)-Rh(2) bond length is 1.51 Å. In the second Rh site, Rh(2) is bonded in a 4-coordinate geometry to one Rh(1) and three equivalent Cu(1) atoms. There is one shorter (2.84 Å) and two longer (3.17 Å) Rh(2)-Cu(1) bond lengths. Cu(1) is bonded in a single-bond geometry to one Sc(1) and three equivalent Rh(2) atoms.
