Abstract: In the title complex, [Ni₂(C₂₈H₃₄N₄O₃)(CH₃CO₂)]ClO₄·0.5CH₃CN, the macrocyclic ligand shows significant deviations from a planar structure. The coordination polyhedra of the Ni atoms can be described as square planar for one of the atoms and as distorted octahedral for the other. The two Ni atoms are bridged by two phenolate O atoms of the macrocycle with an NiNi distance of 2.9612 (5) Å. The acetonitrile solvent molecule occupies a special position on a twofold axis with the H atoms disordered.
