LaOs2P crystallizes in the monoclinic Cm space group. La(1) is bonded in a 9-coordinate geometry to four equivalent La(1), one Os(2), and four equivalent Os(1) atoms. All La(1)-La(1) bond lengths are 3.04 Å. The La(1)-Os(2) bond length is 3.46 Å. There are a spread of La(1)-Os(1) bond distances ranging from 2.99-3.13 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to four equivalent La(1) and one P(1) atom. The Os(1)-P(1) bond length is 0.25 Å. In the second Os site, Os(2) is bonded in a 9-coordinate geometry to one La(1), four equivalent Os(2), and four equivalent P(1) atoms. All Os(2)-Os(2) bond lengths are 3.04 Å. There are a spread of Os(2)-P(1) bond distances ranging from 2.63-2.78 Å. P(1) is bonded in a single-bond geometry to one Os(1) and four equivalent Os(2) atoms.
