Ti6Co7Ga16 crystallizes in the cubic Fm-3m space group. Ti(1) is bonded in a 4-coordinate geometry to four equivalent Co(2), four equivalent Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(2) is bonded to four equivalent Ti(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form a mixture of distorted corner and face-sharing CoTi4Ga8 cuboctahedra. In the second Co site, Co(1) is bonded in a body-centered cubic geometry to eight equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(2) is bonded in a 6-coordinate geometry to three equivalent Ti(1), three equivalent Co(2), and three equivalent Ga(1) atoms. In the second Ga site, Ga(1) is bonded in a 13-coordinate geometry to three equivalent Ti(1), one Co(1), three equivalent Co(2), three equivalent Ga(1), and three equivalent Ga(2) atoms.
