Ti2Ni2In crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) and four equivalent In(1) atoms. In the second Ti site, Ti(2) is bonded in a 6-coordinate geometry to six equivalent Ni(1) and four equivalent In(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to three equivalent Ti(1), three equivalent Ti(2), two equivalent Ni(1), and two equivalent In(1) atoms. In(1) is bonded in a 14-coordinate geometry to four equivalent Ti(1), four equivalent Ti(2), four equivalent Ni(1), and two equivalent In(1) atoms.
Ti2Ni2In crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) and four equivalent In(1) atoms. There are four shorter (2.52 Å) and two longer (2.59 Å) Ti(1)-Ni(1) bond lengths. All Ti(1)-In(1) bond lengths are 2.98 Å. In the second Ti site, Ti(2) is bonded in a 6-coordinate geometry to six equivalent Ni(1) and four equivalent In(1) atoms. There are two shorter (2.56 Å) and four longer (2.60 Å) Ti(2)-Ni(1) bond lengths. All Ti(2)-In(1) bond lengths are 3.04 Å. Ni(1) is bonded in a 10-coordinate geometry to three equivalent Ti(1), three equivalent Ti(2), two equivalent Ni(1), and two equivalent In(1) atoms. There is one shorter (2.46 Å) and one longer (2.72 Å) Ni(1)-Ni(1) bond length. Both Ni(1)-In(1) bond lengths are 2.73 Å. In(1) is bonded in a 14-coordinate geometry to four equivalent Ti(1), four equivalent Ti(2), four equivalent Ni(1), and two equivalent In(1) atoms. Both In(1)-In(1) bond lengths are 3.10 Å.
