The structure described by AgCoO2 crystallizes in the hexagonal P6_3/mmc space group. Co(1) is bonded to six equivalent O(1,2) atoms to form edge-sharing CoO6 octahedra. Ag(1,2) is bonded in a linear geometry to two equivalent O(1,2) atoms. O(1,2) is bonded to three equivalent Co(1) and one Ag(1,2) atom to form a mixture of distorted corner and edge-sharing OCo3Ag tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
