Materials Data on SrV3O7 by Materials Project
SrV3O7 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.45–3.10 Å. There are two inequivalent V4+ sites. In the first V4+ site, V4+ is bonded in a 5-coordinate geometry to five O2- atoms. There is one shorter (1.66 Å) and four longer (2.01 Å) V–O bond length. In the second V4+ site, V4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of V–O bond distances ranging from 1.66–2.00 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one Sr2+ and three V4+ atoms. In the second O2- site, O2- is bonded in a single-bond geometry to two equivalent Sr2+ and one V4+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sr2+ and one V4+ atom.
