Abstract
New hydrazinium fluorocomplexes of iron (N2H5)(3)FeF6, (N2H6)(2)HFeF6. 2H(2)O and (N2H5)(2)FeF5 were isolated from aqueous solutions and char acterized according to their chemical analysis, X-ray powder diffracti on data and Mossbauer spectra. Both (N2H5)(3)FeF6 and (N2H5)(2)HFeF6.2 H(2)O display paramagnetic Mossbauer spectra down to 5 K, while the Mo ssbauer spectra of (N2H5)(2)FeF5 reflect magnetic ordering at 13.5 K a nd a saturation magnetic field of 426 kG. These data are characteristi c of one-dimensional magnetic systems. Studies of the samples thermall y treated up to 738 K confirmed the course of the thermal decompositio n processes, giving mostly mixtures of FeF2 and FeF3.
