RbAg7S4 crystallizes in the tetragonal P4/n space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a body-centered cubic geometry to four equivalent S(1) and four equivalent S(2) atoms. In the second Rb site, Rb(2) is bonded in a body-centered cubic geometry to four equivalent S(1) and four equivalent S(2) atoms. There are four inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted trigonal non-coplanar geometry to one S(1) and two equivalent S(2) atoms. In the second Ag site, Ag(2) is bonded in a distorted trigonal planar geometry to one S(2) and two equivalent S(1) atoms. In the third Ag site, Ag(3) is bonded in a 3-coordinate geometry to one S(2) and three equivalent S(1) atoms. In the fourth Ag site, Ag(4) is bonded in a linear geometry to two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 8-coordinate geometry to one Rb(1), one Rb(2), one Ag(1), two equivalent Ag(2), and three equivalent Ag(3) atoms. In the second S site, S(2) is bonded in a 7-coordinate geometry to one Rb(1), one Rb(2), one Ag(2), one Ag(3), one Ag(4), and two equivalent Ag(1) atoms.
RbAg7S4 crystallizes in the tetragonal P4/n space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a body-centered cubic geometry to four equivalent S(1) and four equivalent S(2) atoms. All Rb(1)-S(1) bond lengths are 3.60 Å.
