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.
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. All K(1)-O(1) bond lengths are 2.81 Å. There are two shorter (2.89 Å) and two longer (3.09 Å) K(1)-O(2) bond lengths. 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. Both Co(1)-O(1) bond lengths are 1.90 Å. Both Co(1)-O(2) bond lengths are 1.85 Å. 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.
