The structure described by Mg14CSb crystallizes in the orthorhombic Amm2 space group. There are seven inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to two equivalent Mg(6), four equivalent Mg(4), and four equivalent Mg(5) atoms. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Mg(7), four equivalent Mg(4), and four equivalent Mg(5) atoms. In the third Mg site, Mg(3) is bonded in a distorted single-bond geometry to two equivalent Mg(7), one C(1), and two equivalent Sb(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 11-coordinate geometry to one Mg(4), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(5), two equivalent Mg(6), and two equivalent Mg(7) atoms. In the fifth Mg site, Mg(5) is bonded in a single-bond geometry to one Mg(1), one Mg(2), one Mg(4), two equivalent Mg(7), and one Sb(1) atom. In the sixth Mg site, Mg(6) is bonded in a single-bond geometry to one Mg(1), two equivalent Mg(4), and one C(1) atom. In the seventh Mg site, Mg(7) is bonded in a 10-coordinate geometry to one Mg(2), two equivalent Mg(3), two equivalent Mg(4), four equivalent Mg(5), and one Sb(1) atom. C(1) is bonded in a distorted see-saw-like geometry to two equivalent Mg(3) and two equivalent Mg(6) atoms. Sb(1) is bonded in a 10-coordinate geometry to two equivalent Mg(7), four equivalent Mg(3), and four equivalent Mg(5) atoms. is represented by the CIF card [CIF]
