La La La La Mo Mo
La2Mo crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one La2Mo cluster. There are two inequivalent La sites. In the first La site, La(1) is bonded in a single-bond geometry to one La(2) and one Mo(1) atom. The La(1)-La(2) bond length is 2.30 Å. The La(1)-Mo(1) bond length is 1.87 Å. In the second La site, La(2) is bonded in a 2-coordinate geometry to one La(1) and one La(2) atom. The La(2)-La(2) bond length is 1.83 Å. Mo(1) is bonded in a distorted single-bond geometry to one La(1) atom.
