Materials Data on Nd2Te5 by Materials Project
Nd2Te5 crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two Nd2Te5 sheets oriented in the (0, 1, 0) direction. there are two inequivalent Nd2+ sites. In the first Nd2+ site, Nd2+ is bonded in a 9-coordinate geometry to nine Te+0.80- atoms. There are five shorter (3.26 Å) and four longer (3.39 Å) Nd–Te bond lengths. In the second Nd2+ site, Nd2+ is bonded in a 9-coordinate geometry to nine Te+0.80- atoms. There are a spread of Nd–Te bond distances ranging from 3.29–3.37 Å. There are four inequivalent Te+0.80- sites. In the first Te+0.80- site, Te+0.80- is bonded in a 5-coordinate geometry to five Nd2+ atoms. In the second Te+0.80- site, Te+0.80- is bonded in a 5-coordinate geometry to five Nd2+ atoms. In the third Te+0.80- site, Te+0.80- is bonded in a 6-coordinate geometry to two equivalent Nd2+ and four equivalent Te+0.80- atoms. All Te–Te bond lengths are 3.14 Å. In the fourth Te+0.80- site, Te+0.80- is bonded in a 8-coordinate geometry to four equivalent Nd2+ and four equivalent Te+0.80- atoms. All Te–Te bond lengths are 3.14 Å.
