The corner-sharing octahedral tilt angles are 52°. B(1) is bonded in a trigonal planar geometry to one O(4) and two equivalent O(1) atoms. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one V(1), one V(4), and one B(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one V(1), one V(2), and one V(3) atom.
