## Two new potentially hexadentate N were prepared from the reaction of 3,5-di-tertbutyl-2-hydroxy benzaldehyde with 1,2-bis(2 0 -aminophenoxy)benzene or 1,2-bis(2 0 -aminophenoxy)-4t-butylbenzene, respectively. From the direct reaction of ligands [H 2 L 1 ] and [H 2 L 2 ] with copper(II) and cobalt(II) salts in methanolic solution and in the presence of N(Et) 3 the neutral [CuL 1 ], [CuL 2 ], [CoL 1 ] and [CoL 2 ] complexes were prepared. All complexes were characterized by IR spectra, elemental analysis, magnetic susceptibility, mass spectra, molar conductance (K m ), UV-Vis spectra and in the case of [CuL 2 ] with X-ray diffraction. X-ray crystal structure of [CuL 2 ] showed that the complex contains copper(II) in a distorted square planar environment of N 2 O 2 donors. Three CH/p interactions were observed in the molecular structure of latter complex.
