TiNiGa crystallizes in the hexagonal P-62m space group. Ti(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), and six equivalent Ga(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Ti(1) and six equivalent Ga(1) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to six equivalent Ti(1) and three equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to six equivalent Ti(1), two equivalent Ni(1), and two equivalent Ni(2) atoms.
TiNiGa crystallizes in the hexagonal P-62m space group. Ti(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), and six equivalent Ga(1) atoms. The Ti(1)-Ni(1) bond length is 2.65 Å. All Ti(1)-Ni(2) bond lengths are 2.60 Å. There are two shorter (2.74 Å) and four longer (2.82 Å) Ti(1)-Ga(1) bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Ti(1) and six equivalent Ga(1) atoms. All Ni(1)-Ga(1) bond lengths are 2.41 Å. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to six equivalent Ti(1) and three equivalent Ga(1) atoms. All Ni(2)-Ga(1) bond lengths are 2.48 Å.
