The material structure described by KCoO2 crystallizes in the orthorhombic Immm space group. K(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Co(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of edge and corner-sharing CoO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted L-shaped geometry to four equivalent K(1) and two equivalent Co(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to four equivalent K(1) and two equivalent Co(1) atoms. is represented by the CIF card [CIF]
