The material described by SrLa(FeO3)2 crystallizes in the trigonal R32 space group. Sr(1) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form distorted SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra and faces with eight equivalent Fe(1)O6 octahedra. La(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. 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 and faces with four equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 14-19°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent Sr(1), two equivalent La(1), and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Sr(1), one La(1), and two equivalent Fe(1) atoms. is represented by the CIF file [CIF]
