Materials Data on Cd3Se by Materials Project
(Cd)2CdSe is alpha Niobium phosphide-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two Cd sheets oriented in the (0, 0, 1) direction and two CdSe sheets oriented in the (0, 0, 1) direction. In each Cd sheet, Cd is bonded in a square co-planar geometry to four equivalent Cd atoms. All Cd–Cd bond lengths are 2.89 Å. In each CdSe sheet, Cd is bonded in a square co-planar geometry to four equivalent Se atoms. All Cd–Se bond lengths are 2.89 Å. Se is bonded in a square co-planar geometry to four equivalent Cd atoms.
