Materials Data on CsAg3Se2 by Materials Project
CsAg3Se2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Cs1+ is bonded in a 7-coordinate geometry to seven Se2- atoms. There are a spread of Cs–Se bond distances ranging from 3.69–3.88 Å. There are three inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a distorted bent 120 degrees geometry to four Se2- atoms. There are a spread of Ag–Se bond distances ranging from 2.64–3.20 Å. In the second Ag1+ site, Ag1+ is bonded in a distorted trigonal planar geometry to three Se2- atoms. There are two shorter (2.70 Å) and one longer (2.75 Å) Ag–Se bond lengths. In the third Ag1+ site, Ag1+ is bonded in a distorted trigonal non-coplanar geometry to three Se2- atoms. There are one shorter (2.64 Å) and two longer (2.78 Å) Ag–Se bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 8-coordinate geometry to four equivalent Cs1+ and four Ag1+ atoms. In the second Se2- site, Se2- is bonded in a 9-coordinate geometry to three equivalent Cs1+ and six Ag1+ atoms.
