Materials Data on Mo2SeS3 by Materials Project

MoSe2(MoS2)3 is Molybdenite-derived structured and crystallizes in the trigonal P3m1 space group. The structure is two-dimensional and consists of three MoS2 sheets oriented in the (0, 0, 1) direction and one MoSe2 sheet oriented in the (0, 0, 1) direction. In each MoS2 sheet, Mo4+ is bonded to six equivalent S2- atoms to form distorted edge-sharing MoS6 pentagonal pyramids. There are three shorter (2.42 Å) and three longer (2.43 Å) Mo–S bond lengths. S2- is bonded in a 3-coordinate geometry to three equivalent Mo4+ atoms. In the MoSe2 sheet, Mo4+ is bonded to six equivalent Se2- atoms to form distorted edge-sharing MoSe6 pentagonal pyramids. All Mo–Se bond lengths are 2.53 Å. Se2- is bonded in a 3-coordinate geometry to three equivalent Mo4+ atoms.
