Materials Data on TaSe2 by Materials Project
TaSe2 is Molybdenite-like structured and crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three TaSe2 sheets oriented in the (0, 0, 1) direction. Ta4+ is bonded to six Se2- atoms to form distorted edge-sharing TaSe6 pentagonal pyramids. All Ta–Se bond lengths are 2.62 Å. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 3-coordinate geometry to three equivalent Ta4+ atoms. In the second Se2- site, Se2- is bonded in a 3-coordinate geometry to three equivalent Ta4+ atoms.
