W2AgBr crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one W2AgBr cluster. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted bent 150 degrees geometry to one Ag(1) and one Br(1) atom. The W(1)-Ag(1) bond length is 1.55 Å. The W(1)-Br(1) bond length is 1.22 Å. In the second W site, W(2) is bonded in a 1-coordinate geometry to one Ag(1) atom. The W(2)-Ag(1) bond length is 1.55 Å. Ag(1) is bonded in a linear geometry to one W(1) and one W(2) atom. Br(1) is bonded in a distorted single-bond geometry to one W(1) atom.
