Ca2CdTe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ca2CdTe clusters. Ca(1) is bonded in an L-shaped geometry to one Cd(1) and one Te(1) atom. The Ca(1)-Cd(1) bond length is 1.56 Å. The Ca(1)-Te(1) bond length is 1.56 Å. Cd(1) is bonded in an L-shaped geometry to two equivalent Ca(1) atoms. Te(1) is bonded in an L-shaped geometry to two equivalent Ca(1) atoms.
