The structure described by BaMg6Cu crystallizes in the orthorhombic Amm2 space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent Mg(3), two equivalent Mg(4), four equivalent Mg(1), and two equivalent Cu(1) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted single-bond geometry to two equivalent Ba(1), two equivalent Mg(3), two equivalent Mg(4), and one Cu(1) atom. In the second Mg site, Mg(2) is bonded in a 2-coordinate geometry to two equivalent Mg(4), four equivalent Mg(3), and two equivalent Cu(1) atoms. In the third Mg site, Mg(3) is bonded in a 10-coordinate geometry to one Ba(1), one Mg(4), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Cu(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Ba(1), two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms. Cu(1) is bonded in a 10-coordinate geometry to two equivalent Ba(1), two equivalent Mg(1), two equivalent Mg(2), and four equivalent Mg(3) atoms. is represented by the CIF file [CIF]
