La La Tc Os
La2TcOs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La2TcOs clusters. There are two inequivalent La sites. In the first La site, La(1) is bonded in a water-like geometry to one Tc(1) and one Os(1) atom. The La(1)-Tc(1) bond length is 1.83 Å. The La(1)-Os(1) bond length is 1.94 Å. In the second La site, La(2) is bonded in a distorted single-bond geometry to one Os(1) atom. The La(2)-Os(1) bond length is 1.94 Å. Tc(1) is bonded in a 1-coordinate geometry to one La(1) atom. Os(1) is bonded in a water-like geometry to one La(1) and one La(2) atom.
