Materials Data on Te2Mo(WS2)3 by Materials Project

MoTe2(WS2)3 is Molybdenite-derived structured and crystallizes in the trigonal P3m1 space group. The structure is two-dimensional and consists of one MoTe2 sheet oriented in the (0, 0, 1) direction and three WS2 sheets oriented in the (0, 0, 1) direction. In the MoTe2 sheet, Mo6+ is bonded in a 6-coordinate geometry to six Te2- atoms. All Mo–Te bond lengths are 2.70 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 3-coordinate geometry to three equivalent Mo6+ atoms. In the second Te2- site, Te2- is bonded to three equivalent Mo6+ atoms to form distorted corner-sharing TeMo3 cuboctahedra. In each WS2 sheet, W+3.33+ is bonded to six equivalent S2- atoms to form distorted edge-sharing WS6 pentagonal pyramids. All W–S bond lengths are 2.44 Å. S2- is bonded in a 3-coordinate geometry to three equivalent W+3.33+ atoms.
