The compound described by SrLa2Mn3O9 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal P-3m1 space group. Sr(1) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form SrO12 cuboctahedra that share corners with six equivalent Sr(1)O12 cuboctahedra, corners with six equivalent La(1)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, faces with two equivalent Mn(2)O6 octahedra, and faces with six equivalent Mn(1)O6 octahedra. La(1) is bonded to three equivalent O(2) and nine equivalent O(1) atoms to form LaO12 cuboctahedra that share corners with three equivalent Sr(1)O12 cuboctahedra, corners with nine equivalent La(1)O12 cuboctahedra, faces with three equivalent Sr(1)O12 cuboctahedra, faces with three equivalent La(1)O12 cuboctahedra, faces with three equivalent Mn(2)O6 octahedra, and faces with five equivalent Mn(1)O6 octahedra. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form MnO6 octahedra that share corners with three equivalent Mn(1)O6 octahedra, corners with three equivalent Mn(2)O6 octahedra, faces with three equivalent Sr(1)O12 cuboctahedra, and faces with five equivalent La(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-4°. In the second Mn site, Mn(2) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra, faces with two equivalent Sr(1)O12 cuboctahedra, and faces with six equivalent La(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 4°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Sr(1), three equivalent La(1), one Mn(1), and one Mn(2) atom. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent Sr(1), two equivalent La(1), and two equivalent Mn(1) atoms. is represented by the CIF card [CIF]
