Tc Tc Au Au
TcAu crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one TcAu cluster. Tc(1) is bonded in a single-bond geometry to one Au(1) atom. The Tc(1)-Au(1) bond length is 1.71 Å. Au(1) is bonded in a bent 150 degrees geometry to one Tc(1) and one Au(1) atom. The Au(1)-Au(1) bond length is 0.35 Å.
