Abstract

BaV2(PO7)2 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. Ba is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of Ba–O bond distances ranging from 2.76–3.31 Å. There are two inequivalent V sites. In the first V site, V is bonded in a 5-coordinate geometry to six O atoms. There are a spread of V–O bond distances ranging from 1.64–2.73 Å. In the second V site, V is bonded in a 5-coordinate geometry to six O atoms. There are a spread of V–O bond distances ranging from 1.64–2.74 Å. There are two inequivalent P sites. In the first P site, P is bonded in a tetrahedral geometry to four O atoms. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. In the second P site, P is bonded in a tetrahedral geometry to four O atoms. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are fourteen inequivalent O sites.
