{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 angstrom 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)degrees. The crystal structure is stabilized by intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions, which link neighbouring molecules into extended chains along the b axis.
