The structure described by Mg2Ti is beta-derived structured and crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded to seven equivalent Mg(1) and five equivalent Ti(1) atoms to form distorted MgMg7Ti5 cuboctahedra that share corners with nine equivalent Mg(1)Mg7Ti5 cuboctahedra, corners with nine equivalent Ti(1)Mg10Ti2 cuboctahedra, edges with four equivalent Ti(1)Mg10Ti2 cuboctahedra, edges with fourteen equivalent Mg(1)Mg7Ti5 cuboctahedra, faces with seven equivalent Ti(1)Mg10Ti2 cuboctahedra, and faces with thirteen equivalent Mg(1)Mg7Ti5 cuboctahedra. Ti(1) is bonded to ten equivalent Mg(1) and two equivalent Ti(1) atoms to form TiMg10Ti2 cuboctahedra that share corners with eighteen equivalent Mg(1)Mg7Ti5 cuboctahedra, edges with eight equivalent Mg(1)Mg7Ti5 cuboctahedra, edges with ten equivalent Ti(1)Mg10Ti2 cuboctahedra, faces with six equivalent Ti(1)Mg10Ti2 cuboctahedra, and faces with fourteen equivalent Mg(1)Mg7Ti5 cuboctahedra. is represented by the CIF card [CIF]
