Materials Data on Ge3Te by Materials Project
(GeGeGe)Te is alpha Niobium phosphide-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two Ge sheets oriented in the (0, 0, 1) direction and two GeTe sheets oriented in the (0, 0, 1) direction. In each Ge sheet, Ge is bonded in a square co-planar geometry to four equivalent Ge atoms. All Ge–Ge bond lengths are 2.92 Å. In each GeTe sheet, Ge is bonded in a square co-planar geometry to four equivalent Te atoms. All Ge–Te bond lengths are 2.92 Å. Te is bonded in a square co-planar geometry to four equivalent Ge atoms.
