CdKCdCa is High Pressure Cadmuum Telluride structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two cadmium;potassium molecules and two CdCa clusters. In each CdCa cluster, Ca(1) is bonded in a single-bond geometry to one Cd(2) atom. The Ca(1)-Cd(2) bond length is 1.00 Å. Cd(2) is bonded in a single-bond geometry to one Ca(1) atom.
