Tc2MnFe is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Tc2MnFe clusters. Tc(1) is bonded in a distorted single-bond geometry to one Mn(1) and one Fe(1) atom. The Tc(1)-Mn(1) bond length is 0.58 Å. The Tc(1)-Fe(1) bond length is 1.25 Å. Mn(1) is bonded in a 2-coordinate geometry to two equivalent Tc(1) atoms. Fe(1) is bonded in a 2-coordinate geometry to two equivalent Tc(1) atoms.
