La La Zr Tc
La2ZrTc crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La2ZrTc clusters. La(1) is bonded in a 2-coordinate geometry to one Zr(1) and one Tc(1) atom. The La(1)-Zr(1) bond length is 2.11 Å. The La(1)-Tc(1) bond length is 2.11 Å. Zr(1) is bonded in a distorted L-shaped geometry to two equivalent La(1) atoms. Tc(1) is bonded in a distorted L-shaped geometry to two equivalent La(1) atoms.
