LaOsCl2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one LaOsCl2 cluster. La(1) is bonded in a distorted single-bond geometry to one Cl(1) and one Cl(2) atom. The La(1)-Cl(1) bond length is 1.66 Å. The La(1)-Cl(2) bond length is 2.45 Å. Os(1) is bonded in a single-bond geometry to one Cl(1) atom. The Os(1)-Cl(1) bond length is 0.64 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted bent 150 degrees geometry to one La(1) and one Os(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one La(1) atom.
