Abstract: The reaction of copper(II) nitrate with the proton-transfer compound piperazinediium pyridine-2,6-dicarboxylate, or (pipzH₂)(pydc), in aqueous solution leads to the formation of the title compound, (C₄H₁₂N₂)[Cu(C₇H₃NO₄)₂]·4H₂O. The title compound is a six-coordinate complex with a distorted octahedral geometry around the central atom. In the crystal structure, a wide range of non-covalent interactions consisting of hydrogen bonding and - stacking connect the various components into a supramolecular structure.
