The structure described by LaSrMn2O5 crystallizes in the orthorhombic P2_12_12_1 space group. Sr(1) is bonded in a 9-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. La(1) is bonded in a 8-coordinate geometry to one O(1), one O(5), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(4), one O(5), 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 Mn(2)O4 tetrahedra.

The corner-sharing octahedral tilt angles range from 23-28°. There are five inequivalent O sites. In the first O site, O(5) is bonded in a 5-coordinate geometry to two equivalent Sr(1), one La(1), one Mn(1), and one Mn(2) atom. In the second O site, O(1) is bonded to one Sr(1), one La(1), and two equivalent Mn(2) atoms to form OSrLaMn2 tetrahedra that share corners with four equivalent O(2)Sr2La2Mn2 octahedra, corners with four equivalent O(3)Sr2La2Mn2 octahedra, and corners with two equivalent O(1)SrLaMn2 tetrahedra. The corner-sharing octahedral tilt angles range from 27-71°. In the third O site, O(2) is bonded to two equivalent Sr(1), two equivalent La(1), and two equivalent Mn(1) atoms to form distorted OSr2La2Mn2 octahedra that share corners with two equivalent O(3)Sr2La2Mn2 octahedra, corners with four equivalent O(1)SrLaMn2 tetrahedra, edges with two equivalent O(3)Sr2La2Mn2 octahedra, faces with two equivalent O(2)Sr2La2Mn2 octahedra, and faces with two equivalent O(3)Sr2La2Mn2 octahedra. The corner-sharing octahedral tilt angles are 1°.

The corner-sharing octahedral tilt angles are 1°. In the fifth O site, O(4) is bonded in a 6-coordinate geometry to two equivalent Sr(1), two equivalent La(1), one Mn(1), and one Mn(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
