CaOsN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Ca(1) is bonded to six equivalent N(1) atoms to form CaN6 octahedra that share corners with six equivalent Os(1)N6 octahedra, edges with six equivalent Ca(1)N6 octahedra, and edges with six equivalent Os(1)N6 octahedra. The corner-sharing octahedral tilt angles are 12°. Os(1) is bonded to six equivalent N(1) atoms to form OsN6 octahedra that share corners with six equivalent Ca(1)N6 octahedra, edges with six equivalent Ca(1)N6 octahedra, and edges with six equivalent Os(1)N6 octahedra. The corner-sharing octahedral tilt angles are 12°. N(1) is bonded to three equivalent Ca(1) and three equivalent Os(1) atoms to form a mixture of edge and corner-sharing NCa3Os3 octahedra. The corner-sharing octahedra are not tilted.
