Ta2AgGa is alpha Po structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ta2AgGa cluster. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 3-coordinate geometry to one Ta(2), one Ag(1), and one Ga(1) atom. The Ta(1)-Ta(2) bond length is 0.33 Å. The Ta(1)-Ag(1) bond length is 0.73 Å. The Ta(1)-Ga(1) bond length is 0.73 Å. In the second Ta site, Ta(2) is bonded in a 3-coordinate geometry to one Ta(1), one Ag(1), and one Ga(1) atom. The Ta(2)-Ag(1) bond length is 0.73 Å. The Ta(2)-Ga(1) bond length is 0.73 Å. Ag(1) is bonded in a distorted single-bond geometry to one Ta(1), one Ta(2), and one Ga(1) atom. The Ag(1)-Ga(1) bond length is 0.33 Å. Ga(1) is bonded in a distorted single-bond geometry to one Ta(1), one Ta(2), and one Ag(1) atom.
