Mg2Ti is Molybdenite structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to nine equivalent Mg(1) and three equivalent Ti(1) atoms to form MgMg9Ti3 cuboctahedra that share corners with six equivalent Ti(1)Mg6Ti6 cuboctahedra, corners with twelve equivalent Mg(1)Mg9Ti3 cuboctahedra, edges with six equivalent Ti(1)Mg6Ti6 cuboctahedra, edges with twelve equivalent Mg(1)Mg9Ti3 cuboctahedra, faces with seven equivalent Ti(1)Mg6Ti6 cuboctahedra, and faces with thirteen equivalent Mg(1)Mg9Ti3 cuboctahedra. Ti(1) is bonded to six equivalent Mg(1) and six equivalent Ti(1) atoms to form TiMg6Ti6 cuboctahedra that share corners with six equivalent Ti(1)Mg6Ti6 cuboctahedra, corners with twelve equivalent Mg(1)Mg9Ti3 cuboctahedra, edges with six equivalent Ti(1)Mg6Ti6 cuboctahedra, edges with twelve equivalent Mg(1)Mg9Ti3 cuboctahedra, faces with six equivalent Ti(1)Mg6Ti6 cuboctahedra, and faces with fourteen equivalent Mg(1)Mg9Ti3 cuboctahedra.
