Materials Data on SmTe3 by Materials Project
SmTe3 crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two SmTe3 sheets oriented in the (0, 1, 0) direction. Sm3+ is bonded in a 9-coordinate geometry to nine Te1- atoms. There are a spread of Sm–Te bond distances ranging from 3.24–3.36 Å. There are two inequivalent Te1- sites. In the first Te1- site, Te1- is bonded in a 5-coordinate geometry to five equivalent Sm3+ atoms. In the second Te1- site, Te1- is bonded in a 6-coordinate geometry to two equivalent Sm3+ and four equivalent Te1- atoms. All Te–Te bond lengths are 3.09 Å.
