description: YV3O9 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a 10-coordinate geometry to six O2- atoms. There are a spread of Y–O bond distances ranging from 2.26–2.50 Å. In the second Y3+ site, Y3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Y–O bond distances ranging from 2.25–2.88 Å. There are six inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to six O2- atoms to form distorted corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 35°. There are a spread of V–O bond distances ranging from 1.74–2.29 Å. In the second V5+ site, V5+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of V–O bond distances ranging from 1.68–1.95 Å. In the third V5+ site, V5+ is bonded to six O2- atoms to form distorted corner-sharing VO6 octahedra.
