Materials Data on AgTe by Materials Project

Abstract

AgTe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to three Ag1+ and four Te1- atoms. There are a spread of Ag–Ag bond distances ranging from 3.01–3.09 Å. There are a spread of Ag–Te bond distances ranging from 2.83–3.14 Å. In the second Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to two equivalent Ag1+ and four Te1- atoms. There are a spread of Ag–Te bond distances ranging from 2.83–3.23 Å. In the third Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to two equivalent Ag1+ and four Te1- atoms. There are a spread of Ag–Te bond distances ranging from 2.87–2.98 Å. There are three inequivalent Te1- sites. In the first Te1- site, Te1- is bonded in a 5-coordinate geometry to four Ag1+ and one Te1- atom. The Te–Te bond length is 2.90 Å. In the second Te1- site, Te1- is bonded in a 1-coordinate geometry to one Ag1+ and two equivalent Te1- atoms. In the third Te1- site, Te1- is bonded in a 7-coordinate geometry to seven Ag1+ atoms.
