Ag4SI crystallizes in the monoclinic C2/m space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 7-coordinate geometry to one Ag(1), two equivalent Ag(2), one S(1), and three equivalent I(1) atoms. In the second Ag site, Ag(2) is bonded in a linear geometry to two equivalent Ag(1) and two equivalent S(1) atoms. S(1) is bonded in a 6-coordinate geometry to two equivalent Ag(1) and four equivalent Ag(2) atoms. I(1) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms.

In the first Ag site, Ag(1) is bonded in a 7-coordinate geometry to one Ag(1), two equivalent Ag(2), one S(1), and three equivalent I(1) atoms. The Ag(1)-Ag(1) bond length is 2.87 Å. Both Ag(1)-Ag(2) bond lengths are 2.99 Å. The Ag(1)-S(1) bond length is 2.70 Å. There is one shorter (3.03 Å) and two longer (3.24 Å) Ag(1)-I(1) bond lengths. In the second Ag site, Ag(2) is bonded in a linear geometry to two equivalent Ag(1) and two equivalent S(1) atoms. Both Ag(2)-S(1) bond lengths are 2.48 Å. S(1) is bonded in a 6-coordinate geometry to two equivalent Ag(1) and four equivalent Ag(2) atoms. I(1) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms.
