Materials Data on Dy2Te by Materials Project

Abstract

Dy2Te crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are six inequivalent Dy sites. In the first Dy site, Dy is bonded in a 3-coordinate geometry to three Te atoms. There are two shorter (3.19 Å) and one longer (3.27 Å) Dy–Te bond lengths. In the second Dy site, Dy is bonded to five Te atoms to form a mixture of distorted edge and corner-sharing DyTe5 square pyramids. There are a spread of Dy–Te bond distances ranging from 3.04–3.12 Å. In the third Dy site, Dy is bonded in a 4-coordinate geometry to four Te atoms. There are a spread of Dy–Te bond distances ranging from 3.10–3.35 Å. In the fourth Dy site, Dy is bonded to five Te atoms to form a mixture of distorted edge and corner-sharing DyTe5 trigonal bipyramids. There are a spread of Dy–Te bond distances ranging from 3.09–3.16 Å. In the fifth Dy site, Dy is bonded in a 4-coordinate geometry to four Te atoms. All Dy–Te bond lengths are 3.13 Å. In the sixth Dy site, Dy is bonded in a distorted L-shaped geometry to two Te atoms. There are one shorter (3.18 Å) and one longer (3.34 Å) Dy–Te bond lengths. There are three inequivalent Te sites. In the first Te site, Te is bonded in a 8-coordinate geometry to eight Dy atoms. In the second Te site, Te is bonded in a 8-coordinate geometry to eight Dy atoms. In the third Te site, Te is bonded to seven Dy atoms to form distorted edge-sharing TeDy7 pentagonal bipyramids.
