CdTe2(CdTe)2 is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CdTe clusters and two CdTe2 clusters. In each CdTe cluster, there are two inequivalent Cd sites. In the first Cd site, Cd(2) is bonded in a single-bond geometry to one Te(2) atom. The Cd(2)-Te(2) bond length is 0.23 Å. In the second Cd site, Cd(3) is bonded in a single-bond geometry to one Te(1) atom. The Cd(3)-Te(1) bond length is 0.23 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a linear geometry to one Cd(3) and one Te(2) atom. The Te(1)-Te(2) bond length is 0.19 Å. In the second Te site, Te(2) is bonded in a linear geometry to one Cd(2) and one Te(1) atom. In each CdTe2 cluster, Cd(1) is bonded in a single-bond geometry to one Te(4) atom. The Cd(1)-Te(4) bond length is 1.76 Å. There are two inequivalent Te sites. In the first Te site, Te(4) is bonded in a linear geometry to one Cd(1) and one Te(3) atom. The Te(4)-Te(3) bond length is 1.70 Å. In the second Te site, Te(3) is bonded in a single-bond geometry to one Te(4) atom.
