The crystal structure described by Au3Ag5S4 is Pb (Zr_0.50 Ti_0.48) O_3-like structured and crystallizes in the triclinic P1 space group. There are three inequivalent Au sites. In the first Au site, Au(1) is bonded in a 6-coordinate geometry to two equivalent Ag(1), two equivalent Ag(4), one S(1), and one S(3) atom. In the second Au site, Au(2) is bonded in a 6-coordinate geometry to one Ag(3), one Ag(5), two equivalent Ag(2), one S(2), and one S(4) atom. In the third Au site, Au(3) is bonded in a 6-coordinate geometry to two equivalent Ag(2), two equivalent Ag(4), one S(1), and one S(4) atom. There are five inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to two equivalent Au(1) and two equivalent S(3) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to two equivalent Au(2), two equivalent Au(3), and two equivalent S(4) atoms. In the third Ag site, Ag(3) is bonded in a 3-coordinate geometry to one Au(2), one S(3), and two equivalent S(2) atoms. In the fourth Ag site, Ag(4) is bonded in a 4-coordinate geometry to two equivalent Au(1), two equivalent Au(3), and two equivalent S(1) atoms. In the fifth Ag site, Ag(5) is bonded in a 2-coordinate geometry to one Au(2), one S(3), and two equivalent S(2) atoms. There are four inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to one Au(1), one Au(3), and two equivalent Ag(4) atoms. In the second S site, S(2) is bonded in a distorted pentagonal planar geometry to one Au(2), two equivalent Ag(3), and two equivalent Ag(5) atoms. In the third S site, S(3) is bonded in a 5-coordinate geometry to one Au(1), one Ag(3), one Ag(5), and two equivalent Ag(1) atoms. In the fourth S site, S(4) is bonded in a distorted rectangular see-saw-like geometry to one Au(2), one Au(3), and two equivalent Ag(2) atoms. is represented by the CIF file [CIF]
