Ag3AuSeS crystallizes in the cubic I2_13 space group. Au(1) is bonded in a 8-coordinate geometry to three equivalent Ag(1), three equivalent Ag(2), one Se(1), and one S(1) atom. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to two equivalent Au(1), two equivalent Se(1), and two equivalent S(1) atoms. In the second Ag site, Ag(2) is bonded in a 6-coordinate geometry to two equivalent Au(1), two equivalent Se(1), and two equivalent S(1) atoms. Se(1) is bonded to one Au(1), three equivalent Ag(1), and three equivalent Ag(2) atoms to form distorted SeAg6Au hexagonal pyramids that share  a cornercorner with one S(1)Ag6Au hexagonal pyramid, corners with six equivalent Se(1)Ag6Au hexagonal pyramids, and edges with six equivalent S(1)Ag6Au hexagonal pyramids. S(1) is bonded to one Au(1), three equivalent Ag(1), and three equivalent Ag(2) atoms to form distorted SAg6Au hexagonal pyramids that share  a cornercorner with one Se(1)Ag6Au hexagonal pyramid, corners with six equivalent S(1)Ag6Au hexagonal pyramids, and edges with six equivalent Se(1)Ag6Au hexagonal pyramids.
