Abstract: In the title complex, [Ni(C₂₆H₂₂N₂O₄)], the Ni^II atom has a slight distortion toward tetrahedral geometry from a square-planar structure, coordinated by two O and two N atoms of the tetradentate salen-type bisoxime 2,2'-[1,1'-(ethylenedioxydinitrilo)diethylidyne]di-1-naphtholate (L^2-) unit, with a mean deviation of 0.022 Å from the N₂O₂ plane. The N- and O-donor atoms are mutually cis. The dihedral angle between two naphthalene systems of the L^2- ligand is 67.59 (4)°. The crystal structure is stabilized by intermolecular C-HO and C-H interactions, which link neighbouring molecules into extended chains along the b axis.
