Materials Data on CsAgSe4 by Materials Project
CsAgSe4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Cs1+ is bonded in a 11-coordinate geometry to eleven Se+0.50- atoms. There are a spread of Cs–Se bond distances ranging from 3.73–4.27 Å. Ag1+ is bonded to five Se+0.50- atoms to form distorted corner-sharing AgSe5 tetrahedra. There are a spread of Ag–Se bond distances ranging from 2.65–3.38 Å. There are four inequivalent Se+0.50- sites. In the first Se+0.50- site, Se+0.50- is bonded in a 2-coordinate geometry to three equivalent Cs1+, two equivalent Ag1+, and one Se+0.50- atom. The Se–Se bond length is 2.40 Å. In the second Se+0.50- site, Se+0.50- is bonded in a 1-coordinate geometry to three equivalent Cs1+, one Ag1+, and two Se+0.50- atoms. The Se–Se bond length is 2.42 Å. In the third Se+0.50- site, Se+0.50- is bonded in a 1-coordinate geometry to three equivalent Cs1+, one Ag1+, and one Se+0.50- atom. The Se–Se bond length is 2.38 Å. In the fourth Se+0.50- site, Se+0.50- is bonded in a 4-coordinate geometry to two equivalent Cs1+, one Ag1+, and two Se+0.50- atoms.
