Sc Cu Cu Rh
ScRhCu2 is Ammonia-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScRhCu2 clusters. Sc(1) is bonded in a single-bond geometry to one Rh(1) atom. The Sc(1)-Rh(1) bond length is 0.63 Å. Rh(1) is bonded in a trigonal non-coplanar geometry to one Sc(1) and two equivalent Cu(1) atoms. Both Rh(1)-Cu(1) bond lengths are 0.49 Å. Cu(1) is bonded in a single-bond geometry to one Rh(1) atom.
