In the title complex, [Ni(CH₃COO)(C₂₈H₂₆N₄)]ClO₄, the Ni^II atom is coordinated by two imine N atoms and two pyridine N atoms of the N-[(E)-1-(6-methyl-2-pyridyl)methylidene]-2-(2-[(E)-1-(6-methyl-2-pyridyl)methylideneamino]phenethyl)aniline donor ligand and two O atoms of the acetate ion in a distorted octahedral coordination. The average Ni-N and Ni-O bond lengths are 2.131 (13) and 2.098 (11) Å, respectively. An intramolecular N-HO interaction occurs. Relatively weak intermolecular C-HO interactions between the ligands and the ClO₄^- ions result in a chain extending along the b axis.
