W2AgTe crystallizes in the monoclinic Cm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one Ag(1) and one Te(1) atom. The W(1)-Ag(1) bond length is 3.08 Å. The W(1)-Te(1) bond length is 1.49 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Ag(1) and one Te(1) atom. The W(2)-Ag(1) bond length is 3.11 Å. The W(2)-Te(1) bond length is 1.49 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted linear geometry to one W(1); one W(2); and six Ag(1,1) atoms. All Ag(1)-Ag(1,1) bond lengths are 3.05 Å. In the second Ag site, Ag(1) is bonded in a distorted linear geometry to one W(1); one W(2); and six Ag(1,1) atoms. The Ag(1)-W(1) bond length is 3.08 Å. The Ag(1)-W(2) bond length is 3.11 Å. Both Ag(1)-Ag(1) bond lengths are 3.05 Å. Te(1) is bonded in a linear geometry to one W(1) and one W(2) atom.
