Materials Data on CoBiTe by Materials Project
CoTeBi crystallizes in the monoclinic P2/m space group. The structure is two-dimensional and consists of two bismuth molecules and one CoTe sheet oriented in the (-1, 0, 1) direction. In the CoTe sheet, there are two inequivalent Co1+ sites. In the first Co1+ site, Co1+ is bonded in a square co-planar geometry to four equivalent Te2- atoms. All Co–Te bond lengths are 2.57 Å. In the second Co1+ site, Co1+ is bonded in a linear geometry to two equivalent Te2- atoms. Both Co–Te bond lengths are 2.54 Å. Te2- is bonded in a 3-coordinate geometry to three Co1+ atoms.
