The title compound, (C 20 H 20 P)[Cd(C 2 N 3 ) 3 ], consists of ethyltriphenylphosphonium (EtPh 3 P + ) cations filling voids in a three‐dimensional anionic cadmium dicyanamide network. In the structure, each Cd II atom is connected to six neighbouring Cd II atoms through six separate dicyanamide ligands, forming cube‐shaped cages. The three‐dimensional anionic network encloses a solvent‐accessible void space of 1851 Å 3 , amounting to 69.3% of the unit‐cell volume. Each cage accommodates only one EtPh 3 P + cation.
