LaOsN3 crystallizes in the monoclinic P2_1/m space group. La(1) is bonded in a 1-coordinate geometry to three equivalent N(2) and four equivalent N(3) atoms. Os(1) is bonded in a T-shaped geometry to one N(1) and two equivalent N(2) atoms. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to one Os(1) and one N(3) atom. In the second N site, N(2) is bonded to three equivalent La(1) and two equivalent Os(1) atoms to form a mixture of distorted edge and corner-sharing NLa3Os2 trigonal bipyramids. In the third N site, N(3) is bonded in a 5-coordinate geometry to four equivalent La(1) and one N(1) atom.
LaOsN3 crystallizes in the monoclinic P2_1/m space group. La(1) is bonded in a 1-coordinate geometry to three equivalent N(2) and four equivalent N(3) atoms. There are two shorter (2.78 Å) and one longer (2.79 Å) La(1)-N(2) bond length. There are a spread of La(1)-N(3) bond distances ranging from 2.47-2.82 Å. Os(1) is bonded in a T-shaped geometry to one N(1) and two equivalent N(2) atoms. The Os(1)-N(1) bond length is 2.02 Å. There is one shorter (1.91 Å) and one longer (1.92 Å) Os(1)-N(2) bond length. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to one Os(1) and one N(3) atom. The N(1)-N(3) bond length is 1.24 Å. In the second N site, N(2) is bonded to three equivalent La(1) and two equivalent Os(1) atoms to form a mixture of distorted edge and corner-sharing NLa3Os2 trigonal bipyramids. In the third N site, N(3) is bonded in a 5-coordinate geometry to four equivalent La(1) and one N(1) atom.
