Materials Data on TeMoSe by Materials Project

MoTeSe is Molybdenite-derived structured and crystallizes in the trigonal P3m1 space group. The structure is two-dimensional and consists of one MoSe2 sheet oriented in the (0, 0, 1) direction and one MoTe2 sheet oriented in the (0, 0, 1) direction. 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 2.57 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 2.72 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 in a 12-coordinate geometry to three equivalent Mo4+ atoms.

Materials Data on Te2Mo3Se4 by Materials Project

MoTe2(MoSe2)2 is Molybdenite-derived structured and crystallizes in the trigonal P3m1 space group. The structure is two-dimensional and consists of two MoSe2 sheets oriented in the (0, 0, 1) direction and one MoTe2 sheet oriented in the (0, 0, 1) direction. In each MoSe2 sheet, Mo4+ is bonded to six equivalent Se2- atoms to form distorted edge-sharing MoSe6 pentagonal pyramids. All Mo–Se bond lengths are 2.56 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. There are three shorter (2.71 Å) and three longer (2.72 Å) Mo–Te bond lengths. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 12-coordinate geometry to three equivalent Mo4+ atoms. In the second Te2- site, Te2- is bonded in a 3-coordinate geometry to three equivalent Mo4+ atoms.
