    Abstract: The binuclear copper(II) and tetranuclear diiron(III)-porphyrin-dicopper(II) complexes with the Schiff-base ligands of N,N'-bis(2-imidazolaldehyde)ethylenediimine, N,N'-bis(2-imidazolaldehyde)-p-phenyldiimine, N,N-bis(acetylpyrazine)ethylenediimine and N,N'-bis(acetylpyrazine)-p-phenyldiimine have been prepared and characterized. The magnetic data indicated that the spin ground states and the magnetic interaction between Cu(II)-Cu(II) or Fe(III)-Cu(II) are dependent on the nature of the bridging ligands. A weak antiferromagnetic interaction between Fe(III) and Cu(II) is evident from the temperature-dependent magnetic measurements. The Mossbauer spectra of iron(III)-porphyrin sites showed an asymmetric quadrupole doublet consistent with high-spin iron(III) S=5/2.
