Abstract: A new polymorph of the title complex, [Ni(C₂₂H₁₈N₄O₆)], has been synthesized and structurally characterized. Ni(II) is coordinated by the four nitrogen donors of the macrocyclic ligand with a distorted square-planar geometry. C-HO hydrogen bonds and stacking interactions link the complex molecules, forming an infinite three-dimensional supramolecular network.
