Materials Data on V2Se2O11 by Materials Project
V2O3(SeO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.60–2.38 Å. Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.64–1.70 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one Se6+ atom. In the second O2- site, O2- is bonded in a linear geometry to two equivalent V5+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one V5+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one V5+ and one Se6+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one V5+ and one Se6+ atom.
