NaNiO2 is Caswellsilverite-like structured and crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded to six equivalent O(1) atoms to form distorted NaO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-16°. Ni(1) is bonded to six equivalent O(1) atoms to form NiO6 octahedra that share corners with six equivalent Na(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-16°. O(1) is bonded to three equivalent Na(1) and three equivalent Ni(1) atoms to form a mixture of distorted edge and corner-sharing ONa3Ni3 octahedra. The corner-sharing octahedra are not tilted.
