Ta Tl Tc Tc
TaTc2Tl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TaTc2Tl cluster. Ta(1) is bonded in a 2-coordinate geometry to one Tc(1) and one Tl(1) atom. The Ta(1)-Tc(1) bond length is 0.61 Å. The Ta(1)-Tl(1) bond length is 0.67 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 3-coordinate geometry to one Ta(1), one Tc(2), and one Tl(1) atom. The Tc(1)-Tc(2) bond length is 0.12 Å. The Tc(1)-Tl(1) bond length is 0.42 Å. In the second Tc site, Tc(2) is bonded in a water-like geometry to one Tc(1) and one Tl(1) atom. The Tc(2)-Tl(1) bond length is 0.38 Å. Tl(1) is bonded in a 3-coordinate geometry to one Ta(1), one Tc(1), and one Tc(2) atom.
