In the second Mn+2.25+ site, Mn+2.25+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with two MnO6 octahedra and corners with two equivalent MnO4 tetrahedra. The corner-sharing octahedra tilt angles range from 33–35°. There are a spread of Mn–O bond distances ranging from 2.03–2.17 Å. In the third Mn+2.25+ site, Mn+2.25+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with two MnO6 octahedra and corners with two equivalent MnO4 tetrahedra. The corner-sharing octahedra tilt angles range from 34–41°. There are a spread of Mn–O bond distances ranging from 2.03–2.14 Å. In the fourth Mn+2.25+ site, Mn+2.25+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent MnO6 octahedra and corners with two MnO4 tetrahedra. The corner-sharing octahedra tilt angles range from 3–21°. There are a spread of Mn–O bond distances ranging from 2.07–2.26 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded to one Sr2+, one La3+, and two Mn+2.25+ atoms to form OSrLaMn2 tetrahedra that share corners with two equivalent OSrLa3Mn2 octahedra and corners with two equivalent OLa2Mn2 tetrahedra. The corner-sharing octahedra tilt angles range from 49–69°. In the second O2- site, O2- is bonded to two La3+ and two Mn+2.25+ atoms to form OLa2Mn2 tetrahedra that share corners with two equivalent OSrLa3Mn2 octahedra and corners with two equivalent OSrLaMn2 tetrahedra. The corner-sharing octahedra tilt angles range from 47–56°. In the third O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Sr2+, one La3+, and two Mn+2.25+ atoms. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to three La3+ and two Mn+2.25+ atoms. In the fifth O2- site, O2- is bonded in a 6-coordinate geometry to one Sr2+, three La3+, and two Mn+2.25+ atoms. In the sixth O2- site, O2- is bonded to one Sr2+, three La3+, and two Mn+2.25+ atoms to form distorted corner-sharing OSrLa3Mn2 octahedra. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one Sr2+, three La3+, and two Mn+2.25+ atoms. In the eighth O2- site, O2- is bonded in a 6-coordinate geometry to one Sr2+, three La3+, and two Mn+2.25+ atoms. In the ninth O2- site, O2- is bonded in a 4-coordinate geometry to two La3+ and two Mn+2.25+ atoms.
