KCoO2 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three 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 to three equivalent K(1) and two equivalent Co(1) atoms to form a mixture of distorted edge and corner-sharing OK3Co2 trigonal bipyramids. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to three equivalent K(1) and two equivalent Co(1) atoms.
KCoO2 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. There are two shorter (2.66 Å) and one longer (2.77 Å) K(1)-O(1) bond length. There are two shorter (2.89 Å) and one longer (3.14 Å) K(1)-O(2) bond length. 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 is one shorter (1.91 Å) and one longer (1.92 Å) Co(1)-O(1) bond length. There is one shorter (1.85 Å) and one longer (1.86 Å) Co(1)-O(2) bond length. There are two inequivalent O sites.
