Abstract: The centrosymmetric title compound, -N,N'-bis(pyridin-4-ylmethylene)hydrazine-bis[diaqua(iminodiacetato)copper(II)], [Cu₂(C₄H₅NO₄)₂(C₁₂H₁₀N₄)(H₂O)₄], features a trans-N₂O₄ donor set that defines a heavily distorted octahedral geometry. Coordination is provided by a tridentate iminodiacetate (ida) dianion, one end of a bidentate bridging N,N'-bis(pyridin-4-ylmethylene)hydrazine ligand, which is disposed about a centre of inversion, and two water molecules. Extensive hydrogen bonding leads to a cohesive crystal structure.
