The corner-sharing octahedral tilt angles are 19°. B(1) is bonded in a trigonal planar geometry to one O(2), one O(4), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(5) is bonded in a distorted rectangular see-saw-like geometry to one V(1), two equivalent Fe(1), and one B(1) atom. In the second O site, O(1) is bonded to two equivalent V(1), one Fe(1), and one Fe(2) atom to form OV2Fe2 tetrahedra that share corners with three equivalent O(3)V2Fe3 square pyramids, corners with three equivalent O(1)V2Fe2 tetrahedra, and  an edgeedge with one O(3)V2Fe3 square pyramid.
