Materials Data on Nd2Te3 by Materials Project
Nd2Te3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of Nd–Te bond distances ranging from 3.25–3.73 Å. In the second Nd3+ site, Nd3+ is bonded to seven Te2- atoms to form a mixture of distorted edge and corner-sharing NdTe7 pentagonal bipyramids. There are a spread of Nd–Te bond distances ranging from 3.20–3.29 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 5-coordinate geometry to five Nd3+ atoms. In the second Te2- site, Te2- is bonded in a 5-coordinate geometry to five Nd3+ atoms. In the third Te2- site, Te2- is bonded to five Nd3+ atoms to form distorted edge-sharing TeNd5 square pyramids.
