The crystal structure described by Sr4Mn2Ga2O11 crystallizes in the orthorhombic Fmmm space group. Sr(1) 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 0-20°. 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. The corner-sharing octahedral tilt angles are 27°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to four equivalent Sr(1), one Mn(1), and one Ga(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to four equivalent Sr(1) and two equivalent Mn(1) atoms. In the third O site, O(3) is bonded to four equivalent Sr(1) and two equivalent Mn(1) atoms to form distorted OSr4Mn2 octahedra that share corners with two equivalent O(3)Sr4Mn2 octahedra, corners with four equivalent O(5)Sr4Ga2 octahedra, edges with two equivalent O(5)Sr4Ga2 octahedra, and edges with two equivalent O(3)Sr4Mn2 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. In the fourth O site, O(4) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Ga(1) atoms.
