Mg6ZnC crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in an L-shaped geometry to one Zn(1) and two equivalent C(1) atoms. In the second Mg site, Mg(2) is bonded in a water-like geometry to two equivalent C(1) atoms. In the third Mg site, Mg(3) is bonded in a 3-coordinate geometry to two equivalent Zn(1) and one C(1) atom. In the fourth Mg site, Mg(4) is bonded in a 2-coordinate geometry to two equivalent Zn(1) atoms. Zn(1) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Mg(4), and four equivalent Mg(3) atoms. C(1) is bonded in a 8-coordinate geometry to two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms.
