Abstract: In the title complex, [Cd₂(C₂₄H₂₆N₄O₂)(ClO₄)₂(H₂O)₂][Cd₂(C₂₄H₂₆N₄O₂)(H₂O)₂](ClO₄)₂, the two distinct macrocycles adopt essentially flat structures. They each encapsulate two Cd atoms. One Cd coordination polyhedron, completed by a water O atom and a perchlorate O atom, is distorted octahedral, while the other is best described as a CdN₂O₃ square-based pyramid, with water in the apical site. Both dinuclear complexes are centrosymmetric.
