Materials Data on LuTe3 by Materials Project
LuTe3 crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two LuTe3 sheets oriented in the (0, 1, 0) direction. Lu3+ is bonded in a 7-coordinate geometry to seven Te1- atoms. There are a spread of Lu–Te bond distances ranging from 3.04–3.40 Å. There are three inequivalent Te1- sites. In the first Te1- site, Te1- is bonded in a 4-coordinate geometry to six equivalent Lu3+ atoms. In the second Te1- site, Te1- is bonded in a distorted single-bond geometry to one Lu3+ and four equivalent Te1- atoms. All Te–Te bond lengths are 3.11 Å. In the third Te1- site, Te1- is bonded in a 4-coordinate geometry to four equivalent Te1- atoms.
