The structure described by LiSr2LaTaO6 crystallizes in the monoclinic Cm space group. Li(1) is bonded in a trigonal non-coplanar geometry to one O(2) and two equivalent O(3) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 9-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(4), and four equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(3) atoms. La(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted LaO6 octahedra that share corners with six equivalent Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 5-9°.
