Materials Data on Te3Mo2Se by Materials Project

(MoTe2)3MoSe2 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 three MoTe2 sheets 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 2.59 Å. Se2- is bonded in a 3-coordinate geometry to three equivalent Mo4+ atoms. In each MoTe2 sheet, Mo4+ is bonded to six Te2- atoms to form distorted edge-sharing MoTe6 pentagonal pyramids. All Mo–Te bond lengths are 2.73 Å. Te2- is bonded in a 3-coordinate geometry to three equivalent Mo4+ atoms. All Te–Mo bond lengths are 2.73 Å.

MoTe2MoTeSe 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 one MoTeSe sheet oriented in the (0, 0, 1) direction. 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 2.73 Å. 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. In the MoTeSe sheet, Mo4+ is bonded in a 6-coordinate geometry to three equivalent Te2- and three equivalent Se2- atoms. All Mo–Te bond lengths are 2.74 Å. All Mo–Se bond lengths are 2.58 Å. Te2- is bonded in a 3-coordinate geometry to three equivalent Mo4+ atoms. Se2- is bonded in a 3-coordinate geometry to three equivalent Mo4+ atoms.
