Materials Data on GaGeTe2 by Materials Project
GaTeGeTe is black P-derived structured and crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of two GaTe sheets oriented in the (0, 0, 1) direction and two GeTe sheets oriented in the (0, 0, 1) direction. In each GaTe sheet, Ga2+ is bonded in a trigonal non-coplanar geometry to three equivalent Te2- atoms. All Ga–Te bond lengths are 2.74 Å. Te2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ga2+ atoms. In each GeTe sheet, Ge2+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent Te2- atoms. All Ge–Te bond lengths are 2.77 Å. Te2- is bonded in a 3-coordinate geometry to three equivalent Ge2+ atoms.
