Sc Sc Cr Ga
ScCrScGa crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScCr clusters and two ScGa clusters. In each ScCr cluster, Sc(1) is bonded in a distorted single-bond geometry to one Cr(1) atom. The Sc(1)-Cr(1) bond length is 1.73 Å. Cr(1) is bonded in a single-bond geometry to one Sc(1) atom. In each ScGa cluster, Sc(2) is bonded in a single-bond geometry to one Ga(1) atom. The Sc(2)-Ga(1) bond length is 0.65 Å. Ga(1) is bonded in a single-bond geometry to one Sc(2) atom.
