Title: Materials Data on TeWS by Materials Project

Abstract

WTe2WS2 is Molybdenite-derived structured and crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of two WS2 sheets oriented in the (0, 0, 1) direction and two WTe2 sheets oriented in the (0, 0, 1) direction. In each WS2 sheet, W4+ is bonded to six equivalent S2- atoms to form distorted edge-sharing WS6 pentagonal pyramids. All W–S bond lengths are 2.46 Å. S2- is bonded in a 3-coordinate geometry to three equivalent W4+ atoms. In each WTe2 sheet, W4+ is bonded to six Te2- atoms to form distorted edge-sharing WTe6 pentagonal pyramids. All W–Te bond lengths are 2.72 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 3-coordinate geometry to three equivalent W4+ atoms. In the second Te2- site, Te2- is bonded in a 12-coordinate geometry to three equivalent W4+ atoms.
