Abstract

Y2TiSnO7 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. there are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.25–2.53 Å. In the second Y3+ site, Y3+ is bonded to eight O2- atoms to form distorted YO8 hexagonal bipyramids that share edges with two equivalent YO8 hexagonal bipyramids, edges with two equivalent SnO6 octahedra, and edges with four equivalent TiO6 octahedra. There are a spread of Y–O bond distances ranging from 2.23–2.61 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four equivalent SnO6 octahedra, and edges with four equivalent YO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 43–51°. There is two shorter (1.97 Å) and four longer (1.99 Å) Ti–O bond length. Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with two equivalent SnO6 octahedra, corners with four equivalent TiO6 octahedra, and edges with two equivalent YO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 51–57°. There are four shorter (2.07more »« less
