LaOsVOs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaOs clusters and two VOs clusters. In each LaOs cluster, La(1) is bonded in a single-bond geometry to one Os(2) atom. The La(1)-Os(2) bond length is 2.08 Å. Os(2) is bonded in a distorted single-bond geometry to one La(1) atom. In each VOs cluster, V(1) is bonded in a single-bond geometry to one Os(1) atom. The V(1)-Os(1) bond length is 1.20 Å. Os(1) is bonded in a single-bond geometry to one V(1) atom.
