In the third Ba site, Ba(3) is bonded in a 10-coordinate geometry to one O(2), one O(3), two equivalent O(4), two equivalent O(6), and four equivalent O(5) atoms. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(3), one O(6), two equivalent O(4), and two equivalent O(5) atoms to form FeO6 octahedra that share corners with three equivalent Fe(3)O4 tetrahedra and  a faceface with one Fe(2)O6 octahedra. In the second Fe site, Fe(2) is bonded to two equivalent O(3) and four equivalent O(4) atoms to form face-sharing FeO6 octahedra. In the third Fe site, Fe(3) is bonded to one O(1), one O(6), and two equivalent O(5) atoms to form FeO4 tetrahedra that share corners with three equivalent Fe(1)O6 octahedra and  a cornercorner with one Fe(3)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 5-26°. There are six inequivalent O sites. In the first O site, O(6) is bonded in a 2-coordinate geometry to one Ba(2), two equivalent Ba(3), one Fe(1), and one Fe(3) atom. In the second O site, O(5) is bonded in a distorted linear geometry to one Ba(1), one Ba(2), two equivalent Ba(3), one Fe(1), and one Fe(3) atom. In the third O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Ba(2) and two equivalent Fe(3) atoms. In the fourth O site, O(2) is bonded in a T-shaped geometry to one Ba(2) and two equivalent Ba(3) atoms. In the fifth O site, O(3) is bonded in a 6-coordinate geometry to one Ba(3), three equivalent Ba(1), one Fe(1), and one Fe(2) atom. In the sixth O site, O(4) is bonded in a 6-coordinate geometry to one Ba(3), three equivalent Ba(1), one Fe(1), and one Fe(2) atom. is represented by the CIF file [CIF]
