A novel polymer resulting from the polycondensation of 2,2′‐diamino‐4,4′‐bithiazole (DABT) with 5,5′‐methylene‐bis‐salicylaldehyde (MBSA) and its ferric complex are described. Analyses of Fourier transform infrared (FT‐IR) and X‐ray photoelectron spectroscopy (XPS) revealed that both bithiazole residue and Schiff‐base moiety acted as coordination sites for Fe 3+ ions in the polymeric matrix. The magnetic behavior of the complex was studied as a function of magnetic field strength (0–60 kOe) at 25 K and as a function of temperature (5–300 K) at a magnetic field strength of 30 kOe. The hysteretic loop was measured at 5 K for the complex showing coercivity ( H c ) of 20 Oe and remnant magnetization ( M r ) of 0.002 emu/g, which is much lower than those of bithiazole‐based polymeric complexes previously reported. The results indicated that the present complex is of the typical characteristics of a soft ferromagnet. Copyright © 2005 John Wiley & Sons, Ltd.
