Materials Data on AgTe4Au by Materials Project
AuAgTe4 is Sylvanite structured and crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Au1+ is bonded to six Te+0.50- atoms to form distorted AuTe6 octahedra that share edges with two equivalent AuTe6 octahedra and edges with four equivalent AgTe6 octahedra. There are a spread of Au–Te bond distances ranging from 2.71–3.43 Å. Ag1+ is bonded to six Te+0.50- atoms to form distorted AgTe6 octahedra that share edges with two equivalent AgTe6 octahedra and edges with four equivalent AuTe6 octahedra. There are a spread of Ag–Te bond distances ranging from 2.80–3.30 Å. There are two inequivalent Te+0.50- sites. In the first Te+0.50- site, Te+0.50- is bonded in a 2-coordinate geometry to two equivalent Au1+, one Ag1+, and one Te+0.50- atom. The Te–Te bond length is 2.85 Å. In the second Te+0.50- site, Te+0.50- is bonded in a 1-coordinate geometry to one Au1+, two equivalent Ag1+, and one Te+0.50- atom.
