La La Tc Ge
La2TcGe crystallizes in the triclinic P1 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 4-coordinate geometry to two equivalent Tc(1) and two equivalent Ge(1) atoms. There is one shorter (1.84 Å) and one longer (2.92 Å) La(1)-Tc(1) bond length. There is one shorter (2.10 Å) and one longer (3.38 Å) La(1)-Ge(1) bond length. In the second La site, La(2) is bonded in a distorted single-bond geometry to one Tc(1) and two equivalent Ge(1) atoms. The La(2)-Tc(1) bond length is 1.23 Å. There is one shorter (1.47 Å) and one longer (3.65 Å) La(2)-Ge(1) bond length. Tc(1) is bonded in a 4-coordinate geometry to one La(2), two equivalent La(1), and one Ge(1) atom. The Tc(1)-Ge(1) bond length is 1.09 Å. Ge(1) is bonded in a 5-coordinate geometry to two equivalent La(1), two equivalent La(2), and one Tc(1) atom.
