Materials Data on TeMo2SeS2 by Materials Project

MoTe2MoSe2(MoS2)2 is Molybdenite-derived structured and crystallizes in the trigonal P3m1 space group. The structure is two-dimensional and consists of two MoS2 sheets oriented in the (0, 0, 1) direction; one MoSe2 sheet oriented in the (0, 0, 1) direction; and one MoTe2 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. All Mo–S bond lengths are 2.44 Å. 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 2.54 Å. Se2- is bonded in a 3-coordinate geometry to three equivalent Mo4+ atoms. In the MoTe2 sheet, Mo4+ is bonded to six Te2- atoms to form distorted edge-sharing MoTe6 pentagonal pyramids. 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 Mo4+ atoms. In the second Te2- site, Te2- is bonded to three equivalent Mo4+ atoms to form distorted corner-sharing TeMo3 cuboctahedra.

In each MoS2 sheet, Mo4+ is bonded to six S2- atoms to form distorted edge-sharing MoS6 pentagonal pyramids. There are three shorter (2.44 Å) and three longer (2.45 Å) Mo–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted T-shaped geometry to three equivalent Mo4+ atoms. In the second S2- site, 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 2.54 Å. Se2- is bonded in a 3-coordinate geometry to three equivalent Mo4+ atoms. In the MoTe2 sheet, Mo4+ is bonded to six equivalent Te2- atoms to form distorted edge-sharing MoTe6 pentagonal pyramids. All Mo–Te bond lengths are 2.70 Å. Te2- is bonded in a 12-coordinate geometry to three equivalent Mo4+ atoms.
