On the highly varied magnetic behavior in a series of mono(α-diimine)dichloroiron(II) complexes. Strong high-temperature one-dimensional ferromagnetic exchange in Fe(phen)Cl2

Mössbauer measurements of the ironorganic polymer [Fe(bipy)ox1.1]n are performed a t 295 and 4.2 K. Theoretical spectra are calculated using a semiclassical spin‐Hamiltonian in the fitting procedure. Iron is submitted in three several states. Two of the three subspectra show magnetic splitting at 4.2 K. This refers to long range order, because a very slowly relaxing paramagnet would be represented by another shape of the spectrum.

Mössbauer spectra of some separately prepared samples of the complex polymer [Fe(bipy)ox1.1]n are recorded at 4.2 K. Magnetically split subspectra are observed. The different shape of one of these subspectra in the several samples can be explained by a decreasing electronic spin–spin relaxation frequency with decreasing concentration of the pertinent iron ion. The assumption of a slowly relaxing paramagnetism is supported by the behaviour of the magnetic susceptibility.
