The material described by Zn(CoO2)4 crystallizes in the trigonal R-3m space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share edges with two equivalent Co(2)O6 octahedra, edges with two equivalent Zn(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. In the second Co site, Co(2) is bonded to six equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Zn(1)O6 octahedra and edges with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 11°. Zn(1) is bonded to six equivalent O(1) atoms to form ZnO6 octahedra that share corners with six equivalent Co(2)O6 octahedra and edges with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 11°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Co(2), two equivalent Co(1), and one Zn(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to three equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
