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.
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. There are four shorter (3.03 Å) and four longer (3.15 Å) Mg(1)-Mg(1) bond lengths. Both Mg(1)-Ti(1) bond lengths are 2.93 Å. There are two shorter (2.79 Å) and two longer (2.93 Å) Mg(1)-Ni(1) bond lengths. Ti(1) is bonded to six equivalent Mg(1) and six equivalent Ni(1) atoms to form distorted face-sharing TiMg6Ni6 cuboctahedra. All Ti(1)-Ni(1) bond lengths are 2.48 Å. Ni(1) is bonded in a 12-coordinate geometry to six equivalent Mg(1), three equivalent Ti(1), and three equivalent Ni(1) atoms. All Ni(1)-Ni(1) bond lengths are 2.60 Å.
