Abstract:

New ternary binuclear complexes, with the formulae, [Cu2A2L](ClO4)4 (1, 2) and [Cu2A2L] (3) have been synthesized. The ligand is L = N,N’-bis(2- pyridylcarbonyl)-1,4-diaminobutane and A = 2,2’- bipyridyl, 1,10-phenanthroline or 2-hydroxybenzoic acid. The ligand and complexes have been characterized by analytical and spectral methods including UV-Vis, FTIR, 1H NMR and ESR. Mass spectrometric data has been used further to support the formation of binuclear complexes. Magnetic studied carried out between LNT and RT and structural parameters of the complexes have been calculated by using universal field method. The complexes are observed to undergo a weak to moderate ferromagnetic coupling between two copper (II) ions with positive J values up to 73 cm-1.

Keywords:

Binucleating ligand, binuclear Cu (II) complexes, σ – bonding bridge and magnetic properties.
