SmAuGa3 crystallizes in the tetragonal I4mm space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Au(1), four equivalent Ga(2), and eight equivalent Ga(1) atoms. Au(1) is bonded in a 5-coordinate geometry to four equivalent Sm(1), one Ga(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 bent 120 degrees geometry to four equivalent Sm(1) and two equivalent Au(1) atoms. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to four equivalent Sm(1) and one Au(1) atom.
SmAuGa3 crystallizes in the tetragonal I4mm space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Au(1), four equivalent Ga(2), and eight equivalent Ga(1) atoms. All Sm(1)-Au(1) bond lengths are 3.34 Å. All Sm(1)-Ga(2) bond lengths are 3.17 Å. There are four shorter (3.32 Å) and four longer (3.58 Å) Sm(1)-Ga(1) bond lengths. Au(1) is bonded in a 5-coordinate geometry to four equivalent Sm(1), one Ga(2), and four equivalent Ga(1) atoms. The Au(1)-Ga(2) bond length is 2.47 Å. All Au(1)-Ga(1) bond lengths are 2.56 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted bent 120 degrees geometry to four equivalent Sm(1) and two equivalent Au(1) atoms. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to four equivalent Sm(1) and one Au(1) atom.
