LaOsN3 crystallizes in the orthorhombic Pmma space group. La(1) is bonded in a distorted body-centered cubic geometry to four equivalent N(1) and four equivalent N(2) atoms. Os(1) is bonded in a square co-planar geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a rectangular see-saw-like geometry to two equivalent La(1), one Os(1), and one N(1) atom. In the second N site, N(2) is bonded to four equivalent La(1) and two equivalent Os(1) atoms to form a mixture of face, corner, and edge-sharing NLa4Os2 octahedra. The corner-sharing octahedral tilt angles are 63°.
LaOsN3 crystallizes in the orthorhombic Pmma space group. La(1) is bonded in a distorted body-centered cubic geometry to four equivalent N(1) and four equivalent N(2) atoms. All La(1)-N(1) bond lengths are 2.68 Å. All La(1)-N(2) bond lengths are 2.72 Å. Os(1) is bonded in a square co-planar geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Os(1)-N(1) bond lengths are 1.98 Å. Both Os(1)-N(2) bond lengths are 1.92 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a rectangular see-saw-like geometry to two equivalent La(1), one Os(1), and one N(1) atom. The N(1)-N(1) bond length is 1.28 Å. In the second N site, N(2) is bonded to four equivalent La(1) and two equivalent Os(1) atoms to form a mixture of face, corner, and edge-sharing NLa4Os2 octahedra.
