In the first O site, O(1) is bonded in a 6-coordinate geometry to four equivalent Sr(1), one Mn(1), and one Mn(2) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Mn(1) atoms. In the third O site, O(3) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Mn(1) atoms to form distorted corner-sharing OSr4Mn2 octahedra. The corner-sharing octahedral tilt angles are 58°. In the fourth O site, O(4,5) is bonded in a 6-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Mn(1) atoms. In the fifth O site, O(6) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Mn(2) atoms. In the sixth O site, O(7,8) is bonded to four equivalent Sr(1) and two equivalent Mn(2) atoms to form a mixture of distorted edge and corner-sharing OSr4Mn2 octahedra. The corner-sharing octahedral tilt angles range from 3-58°. is represented by the Crystallographic Information File (CIF) [CIF]
