La3Os2O10 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.43–2.60 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.43–2.72 Å. Os+5.50+ is bonded to six O2- atoms to form edge-sharing OsO6 octahedra. There are a spread of Os–O bond distances ranging from 1.93–2.01 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal non-coplanar geometry to two equivalent La3+ and one Os+5.50+ atom. In the second O2- site, O2- is bonded to three La3+ and one Os+5.50+ atom to form a mixture of edge and corner-sharing OLa3Os tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three La3+ and one Os+5.50+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one La3+ and two equivalent Os+5.50+ atoms.
