Materials Data on TePb3 by Materials Project
(Pb)2PbTe crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two Pb sheets oriented in the (0, 0, 1) direction and two PbTe sheets oriented in the (0, 0, 1) direction. In each Pb sheet, Pb is bonded in a distorted square co-planar geometry to four equivalent Pb atoms. All Pb–Pb bond lengths are 3.43 Å. In each PbTe sheet, Pb is bonded in a square co-planar geometry to four equivalent Te atoms. All Pb–Te bond lengths are 3.43 Å. Te is bonded in a square co-planar geometry to four equivalent Pb atoms.
