Title: Materials Data on Dy2TiO5 by Materials Project

Abstract

Dy2TiO5 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Dy3+ is bonded to six O2- atoms to form distorted DyO6 pentagonal pyramids that share a cornercorner with one TiO6 octahedra, corners with three equivalent DyO6 pentagonal pyramids, edges with three equivalent TiO6 octahedra, and edges with three equivalent DyO6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 31°. There are a spread of Dy–O bond distances ranging from 2.19–2.40 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with two equivalent DyO6 pentagonal pyramids, and edges with six equivalent DyO6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 32°. There are a spread of Ti–O bond distances ranging from 1.87–2.13 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Dy3+ and one Ti4+ atom. In the second O2- site, O2- is bonded to three equivalent Dy3+ and one Ti4+ atom to form distorted ODy3Ti trigonal pyramids that share a cornercorner with one ODy2Ti2 tetrahedra, corners with three equivalent ODy3Ti trigonal pyramids, edges with two equivalent ODy2Ti2 tetrahedra, and edges with two equivalentmore » ODy3Ti trigonal pyramids. In the third O2- site, O2- is bonded to two equivalent Dy3+ and two equivalent Ti4+ atoms to form distorted ODy2Ti2 tetrahedra that share corners with two equivalent ODy2Ti2 tetrahedra, corners with two equivalent ODy3Ti trigonal pyramids, and edges with four equivalent ODy3Ti trigonal pyramids.« less
