Materials Data on VO3 by Materials Project

VO3 crystallizes in the tetragonal P4_2/ncm space group. The structure is one-dimensional and consists of two VO3 ribbons oriented in the (0, 0, 1) direction. V is bonded in a 5-coordinate geometry to five O atoms. There are a spread of V–O bond distances ranging from 1.72–2.21 Å. There are three inequivalent O sites. In the first O site, O is bonded in a 3-coordinate geometry to two equivalent V and one O atom. The O–O bond length is 1.45 Å. In the second O site, O is bonded in a distorted bent 120 degrees geometry to one V and one O atom. In the third O site, O is bonded in a bent 120 degrees geometry to two equivalent V atoms.
