Synthesis and Spectroscopic Studies of Some Macrocyclic Complexes Derived from Salicylaldehyde

Abstract

The macrocyclic type Tetradentate ligand contain the nitrogen and oxygen as donor atoms have been prepared via the template reaction in two steps with their complexes of some metal ions, the reaction of one equivalent 1,2-phenylendiamine and two equivalent of salicylaldehyde obtained the precursor which the used in the template reaction since the 1,2-dibromoethane and metal salts [Co(II), Cu(II)] were added together as 1:1 ratio to the solution of precursor to form the macrocyclic complexes. The prepared compounds were characterized by Elemental analyses, FT-IR, UV-Vis, and ¹H,¹³C-NMR. The spectral and physical studies show the suggested geometry around the all metals is octahedral.

Keywords: salicylaldehyde, macrocyclic complexes, Copper (II), Cobalt (II) complexes.
