Ta Tl Tl Ga
TaTl2Ga crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TaTl2Ga cluster. Ta(1) is bonded in a distorted single-bond geometry to one Ga(1) atom. The Ta(1)-Ga(1) bond length is 1.49 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a distorted single-bond geometry to one Ga(1) atom. The Tl(1)-Ga(1) bond length is 2.05 Å. In the second Tl site, Tl(2) is bonded in a distorted single-bond geometry to one Ga(1) atom. The Tl(2)-Ga(1) bond length is 1.23 Å. Ga(1) is bonded in a 2-coordinate geometry to one Ta(1), one Tl(1), and one Tl(2) atom.
