Abstract

Dy2TeO6 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Dy–O bond distances ranging from 2.25–2.60 Å. In the second Dy3+ site, Dy3+ is bonded to seven O2- atoms to form distorted DyO7 hexagonal pyramids that share corners with three equivalent TeO6 octahedra, edges with two equivalent DyO7 hexagonal pyramids, and edges with two equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 39–45°. There are a spread of Dy–O bond distances ranging from 2.29–2.47 Å. Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with three equivalent DyO7 hexagonal pyramids and edges with two equivalent DyO7 hexagonal pyramids. There are a spread of Te–O bond distances ranging from 1.93–1.99 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Dy3+ and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Dy3+ and one Te6+ atom. In the third O2- site, O2-more »« less
