Ta Ta Tc Ag
Ta2TcAg crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ta2TcAg cluster. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a distorted single-bond geometry to one Tc(1) and one Ag(1) atom. The Ta(1)-Tc(1) bond length is 1.40 Å. The Ta(1)-Ag(1) bond length is 2.12 Å. In the second Ta site, Ta(2) is bonded in a distorted single-bond geometry to one Tc(1) atom. The Ta(2)-Tc(1) bond length is 1.59 Å. Tc(1) is bonded in a distorted water-like geometry to one Ta(1) and one Ta(2) atom. Ag(1) is bonded in a 1-coordinate geometry to one Ta(1) atom.
