Materials Data on Gd2Te3 by Materials Project
Gd2Te3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded to seven Te2- atoms to form a mixture of distorted edge and corner-sharing GdTe7 pentagonal bipyramids. There are a spread of Gd–Te bond distances ranging from 3.13–3.22 Å. In the second Gd3+ site, Gd3+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of Gd–Te bond distances ranging from 3.19–3.71 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded to five Gd3+ atoms to form a mixture of distorted edge and corner-sharing TeGd5 trigonal bipyramids. In the second Te2- site, Te2- is bonded to five Gd3+ atoms to form a mixture of distorted edge and corner-sharing TeGd5 square pyramids. In the third Te2- site, Te2- is bonded in a 4-coordinate geometry to five Gd3+ atoms.
