In the title complex, [Ni(CH(3)COO)(C(28)H(26)N(4))]ClO(4), the Ni(II) atom is coordinated by two imine N atoms and two pyridine N atoms of the N-[(E)-1-(6-methyl-2-pyrid-yl)methyl-idene]-2-(2-[(E)-1-(6-methyl-2-pyrid-yl)methyl-idene-amino]-pheneth-yl)aniline donor ligand and two O atoms of the acetate ion in a distorted octa-hedral coordination. The average Ni-N and Ni-O bond lengths are 2.131 (13) and 2.098 (11) Å, respectively. An intramolecular N-H⋯O inter-action occurs. Relatively weak inter-molecular C-H⋯O inter-actions between the ligands and the ClO(4) (-) ions result in a chain extending along the b axis.
