The crystal structure described by Sr3La2Fe4CoO15 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R-3m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to six equivalent O(1) and six equivalent O(3) atoms to form SrO12 cuboctahedra that share corners with six equivalent Sr(1)O12 cuboctahedra, corners with six equivalent Sr(2)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, faces with two equivalent Fe(2)O6 octahedra, and faces with six equivalent Fe(1)O6 octahedra. In the second Sr site, Sr(2) is bonded to three equivalent O(3) and nine equivalent O(2) atoms to form SrO12 cuboctahedra that share corners with three equivalent Sr(1)O12 cuboctahedra, corners with three equivalent La(1)O12 cuboctahedra, corners with six equivalent Sr(2)O12 cuboctahedra, faces with three equivalent Sr(2)O12 cuboctahedra, faces with three equivalent La(1)O12 cuboctahedra,  a faceface with one Fe(1)O6 octahedra, faces with three equivalent Co(1)O6 octahedra, and faces with four equivalent Fe(2)O6 octahedra. La(1) is bonded to three equivalent O(1), three equivalent O(2), and six equivalent O(3) atoms to form LaO12 cuboctahedra that share corners with three equivalent Sr(2)O12 cuboctahedra, corners with nine equivalent La(1)O12 cuboctahedra, faces with three equivalent Sr(1)O12 cuboctahedra, faces with three equivalent Sr(2)O12 cuboctahedra,  a faceface with one Co(1)O6 octahedra, faces with three equivalent Fe(2)O6 octahedra, and faces with four equivalent Fe(1)O6 octahedra. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to three equivalent O(1) and three equivalent O(3) atoms to form FeO6 octahedra that share corners with three equivalent Fe(1)O6 octahedra, corners with three equivalent Fe(2)O6 octahedra,  a faceface with one Sr(2)O12 cuboctahedra, faces with three equivalent Sr(1)O12 cuboctahedra, and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-1°. In the second Fe site, Fe(2) is bonded to three equivalent O(2) and three equivalent O(3) atoms to form FeO6 octahedra that share corners with three equivalent Fe(1)O6 octahedra, corners with three equivalent Co(1)O6 octahedra,  a faceface with one Sr(1)O12 cuboctahedra, faces with three equivalent La(1)O12 cuboctahedra, and faces with four equivalent Sr(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 1-4°. Co(1) is bonded to six equivalent O(2) atoms to form CoO6 octahedra that share corners with six equivalent Fe(2)O6 octahedra, faces with two equivalent La(1)O12 cuboctahedra, and faces with six equivalent Sr(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 4°. There are three inequivalent O sites. In the first O site, O(2) is bonded to three equivalent Sr(2), one La(1), one Fe(2), and one Co(1) atom to form a mixture of distorted edge, face, and corner-sharing OSr3LaFeCo octahedra. The corner-sharing octahedral tilt angles range from 0-60°. In the second O site, O(3) is bonded in a distorted linear geometry to one Sr(1), one Sr(2), two equivalent La(1), one Fe(1), and one Fe(2) atom. In the third O site, O(1) is bonded in a distorted linear geometry to two equivalent Sr(1), two equivalent La(1), and two equivalent Fe(1) atoms. is represented by the CIF card [CIF]
