The structure described by Mg3TiNi2 crystallizes in the cubic Fd-3m space group. Mg(1) is bonded in a 14-coordinate geometry to eight equivalent Mg(1), two equivalent Ti(1), and four equivalent Ni(1) atoms. Ti(1) is bonded to six equivalent Mg(1) and six equivalent Ni(1) atoms to form distorted face-sharing TiMg6Ni6 cuboctahedra. Ni(1) is bonded in a 12-coordinate geometry to six equivalent Mg(1), three equivalent Ti(1), and three equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
