(Sn2Te)2(Te)3 is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of four Sn2Te clusters and two Te clusters. In each Sn2Te cluster, there are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one Sn(2) atom. The Sn(1)-Sn(2) bond length is 1.01 Å. In the second Sn site, Sn(2) is bonded in a distorted single-bond geometry to one Sn(1) and one Te(2) atom. The Sn(2)-Te(2) bond length is 1.07 Å. Te(2) is bonded in a distorted single-bond geometry to one Sn(2) atom. In each Te cluster, there are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted single-bond geometry to one Te(3) and one Te(4) atom. The Te(1)-Te(3) bond length is 0.64 Å. The Te(1)-Te(4) bond length is 0.77 Å. In the second Te site, Te(3) is bonded in a distorted single-bond geometry to one Te(1) atom. In the third Te site, Te(4) is bonded in a single-bond geometry to one Te(1) atom.
