A new series of polynuclear iron complexes with polydiimine ligand have been prepared from the Schiff-base condensation of pyridine-2,6-dialdehyde or 2,6-diacetylpyridine with aliphatic diamines. The structures of the complexes are represented by. lbrak.-N=CR-Py-CR=N-(CH/sub 2/)/sub n/-.rbrak./sub 2/ FeSO/sub 4/.bcdot.xH/sub 2/O; where R=H, CH/sub 3/; n=4-10, x=5-8. Mossbauer spectra and magnetic measurements show several complexes have unusual magnetic properties.
