LaTcFe2 crystallizes in the triclinic P1 space group. La(1) is bonded in a 8-coordinate geometry to three equivalent Tc(1), two equivalent Fe(1), and three equivalent Fe(2) atoms. There are a spread of La(1)-Tc(1) bond distances ranging from 2.28-3.50 Å. There is one shorter (2.83 Å) and one longer (2.98 Å) La(1)-Fe(1) bond length. There are a spread of La(1)-Fe(2) bond distances ranging from 2.29-3.47 Å. Tc(1) is bonded in a 2-coordinate geometry to three equivalent La(1) and one Fe(1) atom. The Tc(1)-Fe(1) bond length is 1.79 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 2-coordinate geometry to two equivalent La(1), one Tc(1), and one Fe(2) atom. The Fe(1)-Fe(2) bond length is 1.79 Å. In the second Fe site, Fe(2) is bonded in a 3-coordinate geometry to three equivalent La(1) and one Fe(1) atom.
