Ta Tc Tc Bi
TcTaTcBi crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TcBi cluster and one TcTa cluster. In the TcBi cluster, Tc(1) is bonded in a distorted single-bond geometry to one Bi(1) atom. The Tc(1)-Bi(1) bond length is 1.18 Å. Bi(1) is bonded in a distorted single-bond geometry to one Tc(1) atom. In the TcTa cluster, Ta(1) is bonded in a distorted single-bond geometry to one Tc(2) atom. The Ta(1)-Tc(2) bond length is 1.18 Å. Tc(2) is bonded in a distorted single-bond geometry to one Ta(1) atom.
