ScCuGe crystallizes in the hexagonal P-62m space group. Sc(1) is bonded in a 11-coordinate geometry to one Cu(2), four equivalent Cu(1), and six equivalent Ge(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1) and three equivalent Ge(1) atoms. In the second Cu site, Cu(2) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Ge(1) atoms. Ge(1) is bonded in a 10-coordinate geometry to six equivalent Sc(1), two equivalent Cu(1), and two equivalent Cu(2) atoms.
ScCuGe crystallizes in the hexagonal P-62m space group. Sc(1) is bonded in a 11-coordinate geometry to one Cu(2), four equivalent Cu(1), and six equivalent Ge(1) atoms. The Sc(1)-Cu(2) bond length is 2.72 Å. All Sc(1)-Cu(1) bond lengths are 2.81 Å. There are two shorter (2.92 Å) and four longer (3.09 Å) Sc(1)-Ge(1) bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1) and three equivalent Ge(1) atoms. All Cu(1)-Ge(1) bond lengths are 2.48 Å. In the second Cu site, Cu(2) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Ge(1) atoms. All Cu(2)-Ge(1) bond lengths are 2.63 Å.
