Abstract: In the title compound, [Ni₂(C₂₃H₂₄N₄O₄)(H₂O)₄](ClO₄)₂·4H₂O, each Ni^II atom is coordinated by two bridging phenoxide O atoms, two azomethine N atoms and two water molecules in a slightly distorted octahedral geometry. The crystal packing is stabilized by intermolecular O-HO hydrogen bonds mediated through the water molecules and perchlorate anions. The bis(aminooxy)ethane and diaminopropane groups are disordered across the centre of the molecule, and as a result the complex molecule and the crystal structure is centrosymmetric.
