NaYbO2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded to six O(1,1) atoms to form NaO6 octahedra that share corners with two equivalent Yb(1)O6 octahedra, corners with four equivalent Na(1)O6 octahedra, edges with four equivalent Na(1)O6 octahedra, and edges with eight equivalent Yb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-11°. Yb(1) is bonded to six O(1,1) atoms to form YbO6 octahedra that share corners with two equivalent Na(1)O6 octahedra, corners with four equivalent Yb(1)O6 octahedra, edges with four equivalent Yb(1)O6 octahedra, and edges with eight equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-11°. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Na(1) and three equivalent Yb(1) atoms to form a mixture of corner and edge-sharing ONa3Yb3 octahedra. The corner-sharing octahedral tilt angles range from 0-11°. In the second O site, O(1) is bonded to three equivalent Na(1) and three equivalent Yb(1) atoms to form a mixture of corner and edge-sharing ONa3Yb3 octahedra. The corner-sharing octahedral tilt angles range from 0-11°.
