BaMg6Co crystallizes in the orthorhombic Amm2 space group. Ba(1) is bonded in a 6-coordinate geometry to two equivalent Mg(3), two equivalent Mg(4), and two equivalent Co(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 Mg(4) and one Co(1) atom. In the second Mg site, Mg(2) is bonded in a 2-coordinate geometry to two equivalent Co(1) atoms. In the third Mg site, Mg(3) is bonded in a 2-coordinate geometry to one Ba(1) and two equivalent Co(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 6-coordinate geometry to two equivalent Ba(1) and four equivalent Mg(1) atoms. Co(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.
