ThIrGa crystallizes in the hexagonal P-62m space group. Th(1) is bonded in a 11-coordinate geometry to one Ir(2), four equivalent Ir(1), and six equivalent Ga(1) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(2) is bonded in a 9-coordinate geometry to three equivalent Th(1) and six equivalent Ga(1) atoms. In the second Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent Th(1) and three equivalent Ga(1) atoms. Ga(1) is bonded in a 12-coordinate geometry to six equivalent Th(1), two equivalent Ir(1), two equivalent Ir(2), and two equivalent Ga(1) atoms.
ThIrGa crystallizes in the hexagonal P-62m space group. Th(1) is bonded in a 11-coordinate geometry to one Ir(2), four equivalent Ir(1), and six equivalent Ga(1) atoms. The Th(1)-Ir(2) bond length is 3.00 Å. All Th(1)-Ir(1) bond lengths are 2.99 Å. There are two shorter (3.27 Å) and four longer (3.31 Å) Th(1)-Ga(1) bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir(2) is bonded in a 9-coordinate geometry to three equivalent Th(1) and six equivalent Ga(1) atoms. All Ir(2)-Ga(1) bond lengths are 2.65 Å. In the second Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent Th(1) and three equivalent Ga(1) atoms. All Ir(1)-Ga(1) bond lengths are 2.84 Å. Ga(1) is bonded in a 12-coordinate geometry to six equivalent Th(1), two equivalent Ir(1), two equivalent Ir(2), and two equivalent Ga(1) atoms. Both Ga(1)-Ga(1) bond lengths are 2.92 Å.
