Abstract

Four ternary binuclear complexes, [Cu(A),pichx](ClO (1 and 2) and [Cu(A)pichx](3 and 4) have been synthesized. In the complexes two metal centers are held together by - bonding bridge i.e. pichx= N,N-bis(2-pyridylcarbonyl)-1,6-diaminohexane and A2 is 2,2-bipyridyl or 1,10-phenanthroline or 2-hydroxybenzoic acid or 5-bromo-2-hydroxybenzoic acid coordinated to the metal ions as non-bridging ligands. The complexes were characterized by elemental analyses, conductance, magnetic susceptibility measurement, IR and electronic spectroscopy. The ESI-mass of the complex is consistent with the binuclear formulation. The complexes are observed to undergo a weak to moderate ferromagnetic coupling between two copper (II) ions.
