TaAuSb4 crystallizes in the trigonal R3m space group. Ta(1) is bonded in a single-bond geometry to one Au(1), three equivalent Sb(1), and three equivalent Sb(2) atoms. The Ta(1)-Au(1) bond length is 1.80 Å. All Ta(1)-Sb(1) bond lengths are 3.43 Å. All Ta(1)-Sb(2) bond lengths are 3.49 Å. Au(1) is bonded in a distorted single-bond geometry to one Ta(1) and three equivalent Sb(1) atoms. All Au(1)-Sb(1) bond lengths are 1.55 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 5-coordinate geometry to one Ta(1), one Au(1), one Sb(2), and two equivalent Sb(1) atoms. The Sb(1)-Sb(2) bond length is 1.31 Å. Both Sb(1)-Sb(1) bond lengths are 0.76 Å. In the second Sb site, Sb(2) is bonded in a 6-coordinate geometry to three equivalent Ta(1) and three equivalent Sb(1) atoms.
