Abstract: In the title compound, [CdCu₂(C₁₂H₁₁N₂O₅)₂(H₂O)₃]·2H₂O, the Cu^II atoms are in a square plane of N₂O₂ atoms contributed by the tetradentate Schiff base trianion. The Cu^II atoms are coordinated by one phenolate O atom, one imine N atom, one amido N atom and one carboxylate O atom. The Cd^II atom is connected via the carboxylate groups, forming a heterotrinuclear Cu^II-Cd^II-Cu^II system. The Cd^II atom is seven-coordinate in a pentagonal-bipyramidal geometry with four O atoms from two carboxylate groups and three aqua ligands. The heterotrinuclear molecules are linked to the uncoordinated water molecules by O-HO hydrogen bonds into a three-dimensional framework.
