Abstract

The bi-dentate Schiff base 2-{(E)-[(3-hydroxyphenyl)imino]methyl}phenol derived from the reaction between salicylaldehyde and 3-aminophenol was synthesised ligand. Mixed complexes of (HPIMP) Co(II) and Ni(II) with imidazole (IMD) were synthesised and characterized by spectral analysis (UV-Visible and IR techniques), molar conductivity, atomic absorptionand magnetic susceptibility. The composition of cobalt (II) complex was confirmed to be Co(HPIMP)2(IMD)2, while the nickel(II) forma complex with the structure of Ni(HPIMP)(IMD)2. Special attention was given to the influence of the ligand basicity and the hydrogen bonding on the coordination course. The tautomeric structure of HPIMP was also discussed in terms of its impact on coordination. The coordination surrounding the metal ion seems to emergeas two different structures, the octahedral form in case of cobalt (II) and square planar in case of nickel (II).
