Materials Data on Cd4Te3Se by Materials Project
Cd4Te3Se is Enargite-like structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are four inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to three equivalent Te2- and one Se2- atom to form corner-sharing CdTe3Se tetrahedra. All Cd–Te bond lengths are 2.85 Å. The Cd–Se bond length is 2.70 Å. In the second Cd2+ site, Cd2+ is bonded to one Te2- and three equivalent Se2- atoms to form corner-sharing CdTeSe3 tetrahedra. The Cd–Te bond length is 2.87 Å. All Cd–Se bond lengths are 2.77 Å. In the third Cd2+ site, Cd2+ is bonded to four Te2- atoms to form corner-sharing CdTe4 tetrahedra. There are three shorter (2.85 Å) and one longer (2.86 Å) Cd–Te bond lengths. In the fourth Cd2+ site, Cd2+ is bonded to four Te2- atoms to form corner-sharing CdTe4 tetrahedra. There are three shorter (2.85 Å) and one longer (2.86 Å) Cd–Te bond lengths. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded to four Cd2+ atoms to form TeCd4 tetrahedra that share corners with three equivalent SeCd4 tetrahedra and corners with nine TeCd4 tetrahedra. In the second Te2- site, Te2- is bonded to four Cd2+ atoms to form corner-sharing TeCd4 tetrahedra. In the third Te2- site, Te2- is bonded to four Cd2+ atoms to form TeCd4 tetrahedra that share corners with three equivalent SeCd4 tetrahedra and corners with nine TeCd4 tetrahedra. Se2- is bonded to four Cd2+ atoms to form SeCd4 tetrahedra that share corners with six TeCd4 tetrahedra and corners with six equivalent SeCd4 tetrahedra.
