mp-1821: WSe2 (hexagonal, P6_3/mmc, 194) - Materials Project
WSe2 is Molybdenite structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two WSe2 sheets oriented in the (0, 0, 1) direction. W4+ is bonded to six equivalent Se2- atoms to form distorted edge-sharing WSe6 pentagonal pyramids. All W–Se bond lengths are 2.55 Å.
