BaAuSn3 crystallizes in the tetragonal I4mm space group. Ba(1) is bonded in a 17-coordinate geometry to five equivalent Au(1), four equivalent Sn(1), and eight equivalent Sn(2) atoms. Au(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1), one Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to four equivalent Ba(1) and one Au(1) atom. In the second Sn site, Sn(2) is bonded in a 2-coordinate geometry to four equivalent Ba(1) and two equivalent Au(1) atoms.
BaAuSn3 crystallizes in the tetragonal I4mm space group. Ba(1) is bonded in a 17-coordinate geometry to five equivalent Au(1), four equivalent Sn(1), and eight equivalent Sn(2) atoms. There are four shorter (3.93 Å) and one longer (4.00 Å) Ba(1)-Au(1) bond length. All Ba(1)-Sn(1) bond lengths are 3.76 Å. There are four shorter (3.77 Å) and four longer (3.79 Å) Ba(1)-Sn(2) bond lengths. Au(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1), one Sn(1), and four equivalent Sn(2) atoms.
