Materials Data on V2N4O11 by Materials Project
V2O11(N2)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of sixteen ammonia molecules and four V2O11 clusters. In each V2O11 cluster, there are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.60–2.03 Å. In the second V5+ site, V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.60–2.02 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom. The O–O bond length is 1.33 Å. In the second O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom. The O–O bond length is 1.33 Å. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two V5+ atoms. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom. The O–O bond length is 1.33 Å. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom. The O–O bond length is 1.33 Å. In the eleventh O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom.
