K2CdTe is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one K2CdTe cluster. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Cd(1) atom. The K(1)-Cd(1) bond length is 2.26 Å. In the second K site, K(2) is bonded in a distorted single-bond geometry to one Te(1) atom. The K(2)-Te(1) bond length is 2.84 Å. Cd(1) is bonded in a bent 120 degrees geometry to one K(1) and one Te(1) atom. The Cd(1)-Te(1) bond length is 0.99 Å. Te(1) is bonded in a 2-coordinate geometry to one K(2) and one Cd(1) atom.
