Sc Cu Ru
ScRuCu is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScRuCu clusters. Sc(1) is bonded in a linear geometry to one Ru(1) and one Cu(1) atom. The Sc(1)-Ru(1) bond length is 0.61 Å. The Sc(1)-Cu(1) bond length is 1.08 Å. Ru(1) is bonded in a single-bond geometry to one Sc(1) atom. Cu(1) is bonded in a single-bond geometry to one Sc(1) atom.
