Ti5Ga3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 6-coordinate geometry to two equivalent Ga(2) and four equivalent Ga(1) atoms. In the second Ti site, Ti(2) is bonded in a 6-coordinate geometry to two equivalent Ti(2) and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted q6 geometry to two equivalent Ti(2) and eight equivalent Ti(1) atoms. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to eight equivalent Ti(1) and two equivalent Ga(2) atoms.
Ti5Ga3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 6-coordinate geometry to two equivalent Ga(2) and four equivalent Ga(1) atoms. Both Ti(1)-Ga(2) bond lengths are 2.72 Å. There are a spread of Ti(1)-Ga(1) bond distances ranging from 2.71-2.89 Å. In the second Ti site, Ti(2) is bonded in a 6-coordinate geometry to two equivalent Ti(2) and four equivalent Ga(1) atoms. Both Ti(2)-Ti(2) bond lengths are 2.49 Å. All Ti(2)-Ga(1) bond lengths are 2.70 Å. There are two inequivalent Ga sites.
