LiSrAlO3 crystallizes in the tetragonal P4/mmm space group. Li(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Sr(1) is bonded in a distorted square co-planar geometry to four equivalent O(2) atoms. Al(1) is bonded in a distorted square co-planar geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to two equivalent Li(1) and two equivalent Al(1) atoms. In the second O site, O(2) is bonded to four equivalent Sr(1) and two equivalent Al(1) atoms to form a mixture of corner and edge-sharing OSr4Al2 octahedra. The corner-sharing octahedra are not tilted.
