There are a spread of Li–O bond distances ranging from 1.97–2.28 Å. There are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with five LiO4 tetrahedra and edges with two LiO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.78–1.80 Å. In the second Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with seven LiO4 tetrahedra and edges with four LiO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.76–1.80 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 7-coordinate geometry to one K1+, five Li1+, and one Al3+ atom. In the second O2- site, O2- is bonded in a 6-coordinate geometry to one K1+, five Li1+, and one Al3+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to one K1+, four Li1+, and one Al3+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent K1+, four Li1+, and one Al3+ atom. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to one K1+, four Li1+, and one Al3+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to three K1+, three Li1+, and one Al3+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to three K1+, three Li1+, and one Al3+ atom. In the eighth O2- site, O2- is bonded in a 5-coordinate geometry to two K1+, four Li1+, and one Al3+ atom.« less
