Materials Data on Cd2S by Materials Project
Cd2S crystallizes in the trigonal P3m1 space group. The structure is two-dimensional and consists of one Cd2S sheet oriented in the (0, 0, 1) direction. there are two inequivalent Cd sites. In the first Cd site, Cd is bonded in a 3-coordinate geometry to three equivalent S atoms. All Cd–S bond lengths are 2.60 Å. In the second Cd site, Cd is bonded in a single-bond geometry to one S atom. The Cd–S bond length is 2.52 Å. S is bonded to four Cd atoms to form distorted corner-sharing SCd4 tetrahedra.
