The compound described by Sr2La2Mn4O11 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a distorted q6 geometry to two equivalent O(3) and eight equivalent O(1) atoms. La(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form LaO12 cuboctahedra that share corners with four equivalent La(1)O12 cuboctahedra, faces with four equivalent La(1)O12 cuboctahedra, faces with four equivalent Mn(2)O6 octahedra, and faces with four equivalent Mn(1)O5 square pyramids. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(2) and four equivalent O(1) atoms to form MnO5 square pyramids that share corners with five equivalent Mn(2)O6 octahedra and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the second Mn site, Mn(2) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form MnO6 octahedra that share  a cornercorner with one Mn(2)O6 octahedra, corners with five equivalent Mn(1)O5 square pyramids, and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), two equivalent La(1), one Mn(1), and one Mn(2) atom to form a mixture of distorted face, corner, and edge-sharing OSr2La2Mn2 octahedra. The corner-sharing octahedral tilt angles range from 0-63°. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent La(1), one Mn(1), and one Mn(2) atom. In the third O site, O(3) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Mn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
