SrMnFeBiO6 crystallizes in the trigonal R3 space group. Sr(1) is bonded in a 12-coordinate geometry to six equivalent O(1) and six equivalent O(2) atoms. Mn(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form MnO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 16-21°. 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 Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 16-21°. Bi(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Sr(1), one Mn(1), one Fe(1), and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Sr(1), one Mn(1), one Fe(1), and one Bi(1) atom.
