AgTl2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AgTl2 cluster. Ag(1) is bonded in a distorted single-bond geometry to one Tl(1) atom. The Ag(1)-Tl(1) bond length is 2.76 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 1-coordinate geometry to one Ag(1) and one Tl(2) atom. The Tl(1)-Tl(2) bond length is 1.11 Å. In the second Tl site, Tl(2) is bonded in a distorted single-bond geometry to one Tl(1) atom.
