LiLaO2 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted corner-sharing LiO4 trigonal pyramids. La(1) is bonded in a 7-coordinate geometry to three equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1) and four equivalent La(1) atoms to form a mixture of distorted face, corner, and edge-sharing OLi2La4 octahedra. The corner-sharing octahedral tilt angles range from 57-60°. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Li(1) and three equivalent La(1) atoms.
LiLaO2 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted corner-sharing LiO4 trigonal pyramids. There is one shorter (2.17 Å) and one longer (2.25 Å) Li(1)-O(1) bond length. There is one shorter (1.94 Å) and one longer (2.00 Å) Li(1)-O(2) bond length. La(1) is bonded in a 7-coordinate geometry to three equivalent O(2) and four equivalent O(1) atoms. There are a spread of La(1)-O(2) bond distances ranging from 2.45-2.55 Å.
