BaMg6Ga crystallizes in the orthorhombic Amm2 space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent Mg(1), two equivalent Mg(3), four equivalent Mg(2), and two equivalent Ga(1) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 1-coordinate geometry to one Ba(1), two equivalent Mg(3), and one Ga(1) atom. In the second Mg site, Mg(2) is bonded in a 2-coordinate geometry to two equivalent Ba(1), one Mg(3), and two equivalent Ga(1) atoms. In the third Mg site, Mg(3) is bonded in a 10-coordinate geometry to two equivalent Ba(1), two equivalent Mg(2), two equivalent Mg(4), and four equivalent Mg(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 2-coordinate geometry to two equivalent Mg(3) atoms. Ga(1) is bonded in a 8-coordinate geometry to two equivalent Ba(1), two equivalent Mg(1), and four equivalent Mg(2) atoms.
