Abstract: In the title compound, [Cd(H₂O)₆][Cu(C₁₂H₁₁N₂O₄)]₂·12H₂O, the Cd²⁺ ion lies on an inversion center and the coordination by six aqua ligands is slightly distorted octahedral. The Cu^II atom has a square-planar coordination with two N and two O atoms of the tetradentate Schiff base ligand L^3-, which was derived from alanylglycine and salicylaldehyde. The [Cd(H₂O)₆]²⁺ cations and [CuL]^- anions each form columns along the c axis; these are well segregated from each other.
