The structure described by SmLa7(FeO3)8 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. Sm(1) is bonded to twelve equivalent O(2) atoms to form SmO12 cuboctahedra that share corners with twelve equivalent La(2)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, and faces with eight equivalent Fe(1)O6 octahedra. There are three inequivalent La sites. In the first La site, La(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form LaO12 cuboctahedra that share corners with four equivalent La(3)O12 cuboctahedra, corners with eight equivalent La(1)O12 cuboctahedra, faces with two equivalent Sm(1)O12 cuboctahedra, faces with four equivalent La(2)O12 cuboctahedra, and faces with eight equivalent Fe(1)O6 octahedra. In the second La site, La(2) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form LaO12 cuboctahedra that share corners with four equivalent Sm(1)O12 cuboctahedra, corners with eight equivalent La(2)O12 cuboctahedra, faces with two equivalent La(3)O12 cuboctahedra, faces with four equivalent La(1)O12 cuboctahedra, and faces with eight equivalent Fe(1)O6 octahedra. In the third La site, La(3) is bonded to twelve equivalent O(1) atoms to form LaO12 cuboctahedra that share corners with twelve equivalent La(1)O12 cuboctahedra, faces with six equivalent La(2)O12 cuboctahedra, and faces with eight equivalent Fe(1)O6 octahedra. Fe(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form FeO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra,  a faceface with one Sm(1)O12 cuboctahedra,  a faceface with one La(3)O12 cuboctahedra, faces with three equivalent La(1)O12 cuboctahedra, and faces with three equivalent La(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-1°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one La(1), one La(3), two equivalent La(2), and two equivalent Fe(1) atoms to form a mixture of distorted corner, edge, and face-sharing OLa4Fe2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. In the second O site, O(2) is bonded in a distorted linear geometry to one Sm(1), one La(2), two equivalent La(1), and two equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
