For many years there have been continuous developments and extensive studies on Schiff base coordination compounds [1] [2] [3] . Nevertheless, the chemistry of nickel complexes with multidentate Schiff base ligands has attracted huge attention because such complexes play an important role in bioinorganic chemistry and redox enzyme systems and may provide the basis of models for active sites of biological systems or act as catalysts 4, 5 . Thus, it is quite important to study the structure of

... h metal complexes. Recently, we studied the structure of a four coordinate Ni(II) complex of 2-[(E)-(benzylimino)methyl]-6-bromo-4-chlorophenol. In this structure, the Ni(II) ion is four-coordinate with two Schiff base ligands to form a fairly square planar configuration. The purpose of this study was to elucidate the differences in the crystal structures of four-coordinate Ni(II) complexes of this ligand. Synthesis: To the vigorously stirred solution of 3-bromo-5-chlorosalicylaldehyde (0.2 mmol, 47.2 mg) in EtOH (5 mL), was added dropwise a colourless solution of phenylmethanamine ( 0.2 mmol, 31.4 mg) in solution of EtOH (5 mL) with stirring at room temperature for 1 h. To the resulting orange solution was added NiCl2•6H2O (0.1 mmol, 23.7 mg). The mixture was stirred for 1 h. Green block-shaped crystals of the complex 1 grew after 2 weeks (Scheme-I). The product was filtered, washed with EtOH and dried over anhydrous CaCl2 in vacuo overnight.
