The crystal structure described by Mg6TiC 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 Mg(4), two equivalent Ti(1), and one C(1) atom. In the second Mg site, Mg(2) is bonded in a distorted bent 120 degrees geometry to one Mg(4), two equivalent Ti(1), and two equivalent C(1) atoms. In the third Mg site, Mg(3) is bonded in a 2-coordinate geometry to two equivalent Mg(4) and two equivalent Ti(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 8-coordinate geometry to two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms. Ti(1) is bonded to two equivalent Mg(3), four equivalent Mg(1), four equivalent Mg(2), and two equivalent C(1) atoms to form a mixture of distorted face and corner-sharing TiMg10C2 cuboctahedra. C(1) is bonded in a 6-coordinate geometry to two equivalent Mg(1), four equivalent Mg(2), and two equivalent Ti(1) atoms. is represented by the CIF file [CIF]
