Materials Data on RbAgTeS3 by Materials Project
RbAgTeS3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Rb–S bond distances ranging from 3.41–3.82 Å. Ag1+ is bonded to four S2- atoms to form corner-sharing AgS4 tetrahedra. There are a spread of Ag–S bond distances ranging from 2.57–2.70 Å. Te4+ is bonded in a distorted trigonal non-coplanar geometry to three S2- atoms. There are a spread of Te–S bond distances ranging from 2.38–2.42 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 2-coordinate geometry to three equivalent Rb1+, one Ag1+, and one Te4+ atom. In the second S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Rb1+, two equivalent Ag1+, and one Te4+ atom. In the third S2- site, S2- is bonded in a 5-coordinate geometry to three equivalent Rb1+, one Ag1+, and one Te4+ atom.
