Sc Cu Sn
ScCuSn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScCuSn clusters. Sc(1) is bonded in a single-bond geometry to one Cu(1) atom. The Sc(1)-Cu(1) bond length is 0.55 Å. Cu(1) is bonded in a distorted linear geometry to one Sc(1) and one Sn(1) atom. The Cu(1)-Sn(1) bond length is 1.08 Å. Sn(1) is bonded in a single-bond geometry to one Cu(1) atom.
