LiSr4Mn2Ga2O11 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic C2/m space group. Li(1) is bonded in a square co-planar geometry to two equivalent 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 6-coordinate geometry to one O(2), one O(4), two equivalent O(1), and two equivalent O(5) atoms. In the second Sr site, Sr(2) is bonded in a 11-coordinate geometry to one O(4), two equivalent O(2), two equivalent O(3), two equivalent O(5), and four equivalent O(1) atoms. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with four equivalent Mn(1)O6 octahedra and corners with two equivalent Ga(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 1-24°. Ga(1) is bonded to one O(4), two equivalent O(1), and two equivalent O(5) atoms to form GaO5 trigonal bipyramids that share corners with two equivalent Mn(1)O6 octahedra and corners with three equivalent Ga(1)O5 trigonal bipyramids.
