AgAs3 crystallizes in the triclinic P1 space group. Ag(1) is bonded in a single-bond geometry to one As(1) and one As(2) atom. The Ag(1)-As(1) bond length is 3.37 Å. The Ag(1)-As(2) bond length is 1.84 Å. There are three inequivalent As sites. In the first As site, As(1) is bonded to one Ag(1), one As(3), and four equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing AsAgAs5 octahedra. The corner-sharing octahedra are not tilted. The As(1)-As(3) bond length is 3.08 Å. All As(1)-As(1) bond lengths are 2.88 Å. In the second As site, As(2) is bonded in a distorted bent 150 degrees geometry to one Ag(1) and one As(3) atom. The As(2)-As(3) bond length is 1.65 Å. In the third As site, As(3) is bonded in a distorted single-bond geometry to one As(1) and one As(2) atom.
