Materials Data on VN3O8 by Materials Project
(VO8)2(N2)3 crystallizes in the tetragonal I-42m space group. The structure is zero-dimensional and consists of six ammonia molecules and two VO8 clusters. In each VO8 cluster, V5+ is bonded in a hexagonal bipyramidal geometry to eight O2- atoms. There is four shorter (1.94 Å) and four longer (1.97 Å) V–O bond length. There are two 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 1.36 Å. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom.
