Abstract

Dy2TiO5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded to seven O2- atoms to form distorted DyO7 hexagonal pyramids that share corners with two equivalent DyO7 pentagonal bipyramids, a cornercorner with one TiO5 trigonal bipyramid, edges with four equivalent DyO7 hexagonal pyramids, edges with three equivalent DyO7 pentagonal bipyramids, and edges with two equivalent TiO5 trigonal bipyramids. There are a spread of Dy–O bond distances ranging from 2.34–2.37 Å. In the second Dy3+ site, Dy3+ is bonded to seven O2- atoms to form distorted DyO7 pentagonal bipyramids that share corners with two equivalent DyO7 hexagonal pyramids, corners with three equivalent TiO5 trigonal bipyramids, edges with three equivalent DyO7 hexagonal pyramids, edges with two equivalent DyO7 pentagonal bipyramids, and edges with two equivalent TiO5 trigonal bipyramids. There are a spread of Dy–O bond distances ranging from 2.28–2.39 Å. Ti4+ is bonded to five O2- atoms to form distorted TiO5 trigonal bipyramids that share a cornercorner with one DyO7 hexagonal pyramid, corners with three equivalent DyO7 pentagonal bipyramids, corners with two equivalent TiO5 trigonal bipyramids, edges with two equivalent DyO7 hexagonal pyramids, and edges withmore »« less
