Ag Ag Au Se
AuAg2Se crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AuAg2Se cluster. Au(1) is bonded in a linear geometry to one Ag(1) and one Ag(2) atom. The Au(1)-Ag(1) bond length is 0.80 Å. The Au(1)-Ag(2) bond length is 0.80 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Au(1) and one Se(1) atom. The Ag(1)-Se(1) bond length is 2.42 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Au(1) atom. Se(1) is bonded in a single-bond geometry to one Ag(1) atom.
