Materials Data on CeTe3 by Materials Project
CeTe3 crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two CeTe3 sheets oriented in the (0, 1, 0) direction. Ce4+ is bonded in a 9-coordinate geometry to nine Te+1.33- atoms. There are a spread of Ce–Te bond distances ranging from 3.26–3.30 Å. There are three inequivalent Te+1.33- sites. In the first Te+1.33- site, Te+1.33- is bonded in a 2-coordinate geometry to two equivalent Ce4+ and four equivalent Te+1.33- atoms. All Te–Te bond lengths are 3.12 Å. In the second Te+1.33- site, Te+1.33- is bonded in a 2-coordinate geometry to two equivalent Ce4+ and four equivalent Te+1.33- atoms. In the third Te+1.33- site, Te+1.33- is bonded in a 5-coordinate geometry to five equivalent Ce4+ atoms.
