Materials Data on Ag2Bi2SeS3 by Materials Project
Abstract
Ag2Bi2SeS3 is alpha Po-derived structured and crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded to one Se2- and five S2- atoms to form AgSeS5 octahedra that share corners with two equivalent BiSeS5 octahedra, corners with four equivalent AgSeS5 octahedra, edges with four equivalent AgSe2S4 octahedra, and edges with eight BiSeS5 octahedra. The corner-sharing octahedra tilt angles range from 0–4°. The Ag–Se bond length is 2.92 Å. There are a spread of Ag–S bond distances ranging from 2.82–2.89 Å. In the second Ag1+ site, Ag1+ is bonded to two equivalent Se2- and four S2- atoms to form AgSe2S4 octahedra that share corners with two equivalent BiSe2S4 octahedra, corners with four equivalent AgSe2S4 octahedra, edges with four equivalent AgSeS5 octahedra, and edges with eight BiSeS5 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. Both Ag–Se bond lengths are 2.82 Å. There are two shorter (2.89 Å) and two longer (2.95 Å) Ag–S bond lengths. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded to one Se2- and five S2- atoms to form BiSeS5 octahedra that share corners with twomore »
