KLiNiO2 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Li(1) is bonded to one O(2) and three equivalent O(1) atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. Ni(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent K(1), three equivalent Li(1), and one Ni(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to four equivalent K(1), one Li(1), and two equivalent Ni(1) atoms.
KLiNiO2 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Both K(1)-O(1) bond lengths are 2.66 Å. There are a spread of K(1)-O(2) bond distances ranging from 2.82-3.13 Å. Li(1) is bonded to one O(2) and three equivalent O(1) atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. The Li(1)-O(2) bond length is 2.12 Å. There are two shorter (1.95 Å) and one longer (2.06 Å) Li(1)-O(1) bond length. Ni(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. The Ni(1)-O(1) bond length is 1.83 Å. There is one shorter (1.90 Å) and one longer (1.91 Å) Ni(1)-O(2) bond length. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent K(1), three equivalent Li(1), and one Ni(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to four equivalent K(1), one Li(1), and two equivalent Ni(1) atoms.
