Abstract
Y4V6O21 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to eight O2- atoms to form distorted YO8 hexagonal bipyramids that share edges with six VO6 octahedra. There are a spread of Y–O bond distances ranging from 2.13–2.58 Å. In the second Y3+ site, Y3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.05–2.88 Å. In the third Y3+ site, Y3+ is bonded to eight O2- atoms to form distorted YO8 hexagonal bipyramids that share edges with four YO8 hexagonal bipyramids and edges with six VO6 octahedra. There are a spread of Y–O bond distances ranging from 2.14–2.55 Å. In the fourth Y3+ site, Y3+ is bonded to eight O2- atoms to form distorted YO8 hexagonal bipyramids that share edges with four equivalent YO8 hexagonal bipyramids and edges with six VO6 octahedra. There are a spread of Y–O bond distances ranging from 2.16–2.53 Å. There are six inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six VO6more »
