OsN2 is Marcasite structured and crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Os6+ is bonded to six equivalent N3- atoms to form OsN6 octahedra that share corners with eight equivalent OsN6 octahedra, corners with six equivalent NOs3N tetrahedra, and edges with two equivalent OsN6 octahedra. The corner-sharing octahedral tilt angles are 66°. There are two shorter (2.07 Å) and four longer (2.11 Å) Os–N bond lengths. N3- is bonded to three equivalent Os6+ and one N3- atom to form distorted NOs3N tetrahedra that share corners with three equivalent OsN6 octahedra, corners with thirteen equivalent NOs3N tetrahedra, and an edgeedge with one NOs3N tetrahedra. The corner-sharing octahedra tilt angles range from 63–67°. The N–N bond length is 1.41 Å.
