LaOsN3 crystallizes in the monoclinic P2_1/c space group. La(1) is bonded in a 7-coordinate geometry to two equivalent N(2), two equivalent N(3), and three equivalent N(1) atoms. Os(1) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form distorted edge-sharing OsN4 tetrahedra. There are three inequivalent N sites. In the first N site, N(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent La(1) and one Os(1) atom. In the second N site, N(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent La(1) and one Os(1) atom. In the third N site, N(3) is bonded in a distorted square co-planar geometry to two equivalent La(1) and two equivalent Os(1) atoms.
LaOsN3 crystallizes in the monoclinic P2_1/c space group. La(1) is bonded in a 7-coordinate geometry to two equivalent N(2), two equivalent N(3), and three equivalent N(1) atoms. There is one shorter (2.48 Å) and one longer (2.52 Å) La(1)-N(2) bond length. There is one shorter (2.56 Å) and one longer (2.67 Å) La(1)-N(3) bond length. There are a spread of La(1)-N(1) bond distances ranging from 2.62-2.72 Å. Os(1) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form distorted edge-sharing OsN4 tetrahedra.
