The compound described by Na3Co2SbO6 is Caswellsilverite-derived structured and crystallizes in the triclinic P-1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NaO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra, corners with four equivalent Co(1)O6 octahedra, edges with two equivalent Sb(1)O6 octahedra, edges with four equivalent Co(1)O6 octahedra, and edges with six equivalent Na(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-11°. In the second Na site, Na(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NaO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra, corners with four equivalent Co(1)O6 octahedra, edges with two equivalent Sb(1)O6 octahedra, edges with three equivalent Na(1)O6 octahedra, edges with three equivalent Na(2)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 7-14°. Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share corners with two equivalent Na(1)O6 octahedra, corners with four equivalent Na(2)O6 octahedra, edges with two equivalent Na(1)O6 octahedra, edges with three equivalent Co(1)O6 octahedra, edges with three equivalent Sb(1)O6 octahedra, and edges with four equivalent Na(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-14°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with two equivalent Na(1)O6 octahedra, corners with four equivalent Na(2)O6 octahedra, edges with two equivalent Na(1)O6 octahedra, edges with four equivalent Na(2)O6 octahedra, and edges with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 7-11°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), two equivalent Na(2), two equivalent Co(1), and one Sb(1) atom to form a mixture of corner and edge-sharing ONa3Co2Sb octahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the second O site, O(2) is bonded to one Na(1), two equivalent Na(2), two equivalent Co(1), and one Sb(1) atom to form a mixture of corner and edge-sharing ONa3Co2Sb octahedra. The corner-sharing octahedral tilt angles range from 0-7°. In the third O site, O(3) is bonded to one Na(1), two equivalent Na(2), two equivalent Co(1), and one Sb(1) atom to form a mixture of corner and edge-sharing ONa3Co2Sb octahedra.
