The compound described by LiLaO2 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded in a distorted trigonal planar geometry to one O(1) and two equivalent O(2) atoms. La(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing LaO6 octahedra. The corner-sharing octahedral tilt angles range from 20-55°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Li(1) and three equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing OLiLa3 tetrahedra. 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. is represented by the Crystallographic Information File (CIF) [CIF]
