The crystal structure described by Mg6FeC crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a single-bond geometry to two equivalent Fe(1) and one C(1) atom. In the second Mg site, Mg(2) is bonded in a distorted L-shaped geometry to two equivalent Fe(1) and two equivalent C(1) atoms. In the third Mg site, Mg(3) is bonded in a distorted L-shaped geometry to two equivalent Fe(1) atoms. In the fourth Mg site, Mg(4) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Fe(1) and two equivalent C(1) atoms. Fe(1) is bonded to two equivalent Mg(3), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms to form a mixture of distorted face and corner-sharing FeMg12 cuboctahedra. C(1) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Mg(4), and four equivalent Mg(2) atoms. is represented by the CIF file [CIF]
