Materials Data on Ag3AuSe2 by Materials Project
Ag3AuSe2 crystallizes in the cubic I4_132 space group. The structure is three-dimensional. Au1+ is bonded in a 8-coordinate geometry to six equivalent Ag1+ and two equivalent Se2- atoms. All Au–Ag bond lengths are 3.08 Å. Both Au–Se bond lengths are 2.50 Å. Ag1+ is bonded in a 6-coordinate geometry to two equivalent Au1+ and four equivalent Se2- atoms. There are two shorter (2.79 Å) and two longer (2.92 Å) Ag–Se bond lengths. Se2- is bonded in a 7-coordinate geometry to one Au1+ and six equivalent Ag1+ atoms.
