Materials Data on Cs2Se by Materials Project
Cs2Se is Cotunnite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to four equivalent Se2- atoms. There are a spread of Cs–Se bond distances ranging from 3.67–4.13 Å. In the second Cs1+ site, Cs1+ is bonded to four equivalent Se2- atoms to form a mixture of corner and edge-sharing CsSe4 tetrahedra. There are a spread of Cs–Se bond distances ranging from 3.58–3.66 Å. Se2- is bonded in a 8-coordinate geometry to eight Cs1+ atoms.
