ScCu3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Sc(1) is bonded in a distorted body-centered cubic geometry to six equivalent Cu(1) and eight equivalent Cu(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 14-coordinate geometry to six equivalent Sc(1) and eight equivalent Cu(2) atoms. In the second Cu site, Cu(2) is bonded to four equivalent Sc(1) and four equivalent Cu(1) atoms to form a mixture of distorted face, corner, and edge-sharing CuSc4Cu4 tetrahedra.
