Ta2TcMn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ta2TcMn cluster. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 2-coordinate geometry to one Tc(1) and one Mn(1) atom. The Ta(1)-Tc(1) bond length is 1.00 Å. The Ta(1)-Mn(1) bond length is 1.10 Å. In the second Ta site, Ta(2) is bonded in a single-bond geometry to one Mn(1) atom. The Ta(2)-Mn(1) bond length is 0.76 Å. Tc(1) is bonded in a single-bond geometry to one Ta(1) atom. Mn(1) is bonded in a 2-coordinate geometry to one Ta(1) and one Ta(2) atom.
