Materials Data on Cs2Cd3Te4 by Materials Project
Cs2Cd3Te4 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Cs1+ is bonded in a body-centered cubic geometry to eight equivalent Te2- atoms. There are a spread of Cs–Te bond distances ranging from 4.00–4.16 Å. There are two inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to four equivalent Te2- atoms to form a mixture of edge and corner-sharing CdTe4 tetrahedra. There are two shorter (2.86 Å) and two longer (2.97 Å) Cd–Te bond lengths. In the second Cd2+ site, Cd2+ is bonded to four equivalent Te2- atoms to form a mixture of edge and corner-sharing CdTe4 tetrahedra. All Cd–Te bond lengths are 2.90 Å. Te2- is bonded in a 7-coordinate geometry to four equivalent Cs1+ and three Cd2+ atoms.
