LiSrAlO3 crystallizes in the monoclinic Cm space group. Li(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. Sr(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Al(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted corner-sharing AlO5 square pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Li(1), two equivalent Sr(1), and two equivalent Al(1) atoms. In the second O site, O(2) is bonded to one Li(1), four equivalent Sr(1), and one Al(1) atom to form a mixture of distorted corner and edge-sharing OSr4LiAl octahedra. The corner-sharing octahedral tilt angles are 5°.
LiSrAlO3 crystallizes in the monoclinic Cm space group. Li(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. The Li(1)-O(2) bond length is 1.92 Å. There are two shorter (1.94 Å) and two longer (2.10 Å) Li(1)-O(1) bond lengths. Sr(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two shorter (2.71 Å) and two longer (2.82 Å) Sr(1)-O(1) bond lengths. There are a spread of Sr(1)-O(2) bond distances ranging from 2.60-2.63 Å. Al(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted corner-sharing AlO5 square pyramids. The Al(1)-O(2) bond length is 1.80 Å.
