LaTcFe2 crystallizes in the triclinic P1 space group. La(1) is bonded in a rectangular see-saw-like geometry to two equivalent Fe(1) and two equivalent Fe(2) atoms. There is one shorter (2.10 Å) and one longer (2.29 Å) La(1)-Fe(1) bond length. There is one shorter (2.07 Å) and one longer (2.26 Å) La(1)-Fe(2) bond length. Tc(1) is bonded in a 10-coordinate geometry to four equivalent Tc(1), two equivalent Fe(2), and four equivalent Fe(1) atoms. There are two shorter (2.96 Å) and two longer (3.09 Å) Tc(1)-Tc(1) bond lengths. There is one shorter (2.55 Å) and one longer (2.70 Å) Tc(1)-Fe(2) bond length. There are a spread of Tc(1)-Fe(1) bond distances ranging from 2.67-3.31 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted L-shaped geometry to two equivalent La(1) and four equivalent Tc(1) atoms. In the second Fe site, Fe(2) is bonded in a distorted L-shaped geometry to two equivalent La(1) and two equivalent Tc(1) atoms.
