Ag7(SI)2 crystallizes in the triclinic P1 space group. There are seven inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to three equivalent Ag(4) and three equivalent I(2) atoms to form distorted AgAg3I3 octahedra that share corners with three equivalent I(1)Ag4 trigonal pyramids and edges with six equivalent Ag(1)Ag3I3 octahedra. In the second Ag site, Ag(2) is bonded in a distorted linear geometry to one S(2) and one I(2) atom. In the third Ag site, Ag(3) is bonded in a 4-coordinate geometry to one S(1) and three equivalent I(1) atoms. In the fourth Ag site, Ag(4) is bonded in a distorted single-bond geometry to three equivalent Ag(1) and one I(1) atom. In the fifth Ag site, Ag(5) is bonded in a linear geometry to one S(1) and one S(2) atom. In the sixth Ag site, Ag(6) is bonded in a bent 150 degrees geometry to two equivalent S(1) atoms. In the seventh Ag site, Ag(7) is bonded in a 3-coordinate geometry to three equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted see-saw-like geometry to one Ag(3), one Ag(5), and two equivalent Ag(6) atoms. In the second S site, S(2) is bonded in a distorted pentagonal planar geometry to one Ag(2), one Ag(5), and three equivalent Ag(7) atoms. There are two inequivalent I sites. In the first I site, I(1) is bonded to one Ag(4) and three equivalent Ag(3) atoms to form distorted IAg4 trigonal pyramids that share corners with three equivalent Ag(1)Ag3I3 octahedra and corners with six equivalent I(1)Ag4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 58-63°. In the second I site, I(2) is bonded in a rectangular see-saw-like geometry to one Ag(2) and three equivalent Ag(1) atoms.
