Ta2AuSb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ta2AuSb clusters. Ta(1) is bonded in a 3-coordinate geometry to one Ta(1), one Au(1), and one Sb(1) atom. The Ta(1)-Ta(1) bond length is 0.46 Å. The Ta(1)-Au(1) bond length is 1.25 Å. The Ta(1)-Sb(1) bond length is 0.72 Å. Au(1) is bonded in a 2-coordinate geometry to two equivalent Ta(1) atoms. Sb(1) is bonded in a 2-coordinate geometry to two equivalent Ta(1) atoms.
