Cu6GeSb is Sodium arsenide-derived structured and crystallizes in the hexagonal P-6m2 space group. There are four inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted trigonal planar geometry to six equivalent Cu(4) and three equivalent Ge(1) atoms. In the second Cu site, Cu(2) is bonded in a distorted trigonal planar geometry to six equivalent Cu(3) and three equivalent Sb(1) atoms. In the third Cu site, Cu(3) is bonded in a 11-coordinate geometry to one Cu(3), three equivalent Cu(2), three equivalent Cu(4), one Ge(1), and three equivalent Sb(1) atoms. In the fourth Cu site, Cu(4) is bonded in a 11-coordinate geometry to one Cu(4), three equivalent Cu(1), three equivalent Cu(3), three equivalent Ge(1), and one Sb(1) atom. Ge(1) is bonded in a 11-coordinate geometry to two equivalent Cu(3), three equivalent Cu(1), and six equivalent Cu(4) atoms. Sb(1) is bonded in a 11-coordinate geometry to two equivalent Cu(4), three equivalent Cu(2), and six equivalent Cu(3) atoms.
