文摘

Two polymeric ferro-complexes were first synthesized from FeSO₄·7H₂O and poly(Schiff base)s. The poly(Schiff base)s were prepared by polycondensation of 5,5′-dimethyl-2,2′-diamino-4,4′-bithiazole (MDABT) with oxalic aldehyde and isophthalaldehyde, respectively. The structures of polymers and complexes were characterized by IR and ¹H NMR spectra. The Fe contents of complexes were measured by X-ray spectrometer. The magnetic behavior of the complexes was examined as a function of magnetic field strength at 4 K and as a function of temperature (4–300 K). The results show that PMTOA-Fe²⁺ is a soft ferromagnet while PMTIA-Fe²⁺ exhibits features of an antiferromagnet.
