Materials Data on WSe2 by 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. Se2- is bonded in a 3-coordinate geometry to three equivalent W4+ atoms.

二硒化钨（WSe₂）具有辉钼矿型晶体结构，结晶于六方晶系P6₃/mmc空间群。该结构为二维构型，包含两层沿(0, 0, 1)晶向取向的二硒化钨片层。四价钨阳离子（W⁴+）与六个等价的二价硒阴离子（Se²⁻）配位，形成畸变的共棱WSe₆五角锥。所有W–Se键长均为2.55埃（Å）。二价硒阴离子以三配位几何构型与三个等价的四价钨阳离子配位。
