Crystal structure of [2-({2-[(2-azanidyl­benzyl­idene)amino]­benzyl­idene}amino)-4-chloro­phenol­ato]nickel(II)

The title complex, [Ni(C(20)H(14)ClN(3)O)], with an asymmetrically chloride-appended Schiff base ligand has been synthesized and structurally characterized at 100 K. In the compound, the central nickel(II) ion has a square-planar coordination geometry with N(3)O donors of the π-conjugated tetra­dentate Schiff base ligand. In the crystal, the complexes are connected into an inversion dimer via an Ni⋯Ni inter­action [3.1753 (5) Å] and a pair of π–π inter­actions [centroid–centroid distance = 3.8416 (16) Å]. The dimers are linked via a C—H⋯Cl hydrogen bond, forming a chain along the c-axis direction. The dimer chains inter­act with each other through π–π inter­actions [centroid–centroid distance = 3.8736 (16) Å], forming a layer expanding parallel to the ac plane.
