Abstract

We have investigated the ferromagnetic states for (n-CnH2n + 1)4N[FeIIFeIII(dto)3] (n = 3–6; dto = C2O2S2) by means of 57Fe Mössbauer spectroscopy. The major component of the spin configuration in the ferromagnetic states for n = 3 and 4 is the low-temperature phase (LTP) with the FeIII (S = 5/2) and FeII (S = 0) states. The high-temperature phase (HTP) of n = 4 remains by more than 20%, which is consistent with two ferromagnetic transitions (TC = 7 & 13 K). Moreover, it was revealed that the Mössbauer spectra in the ferromagnetic states for n = 5 and 6 correspond to the HTP consisting of the FeII (S = 2) and FeIII (S = 1/2) states.
