{2,2′-[1,1′-(Ethyl­enedioxy­dinitrilo)diethyl­idyne]di-1-naphtholato}nickel(II)

In the title complex, [Ni(C(26)H(22)N(2)O(4))], 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 N(2)O(2) 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—H⋯O and C—H⋯π inter­actions, which link neighbouring mol­ecules into extended chains along the b axis.
