Linkage-isomerization and charge-transfer in the formation of iron mixed valence complexes, (n-C3H7)4N[Fe IIFeIII(dto)3] (dto C2O 2S2) and (n-C4H9) 4N[FeIIFeIII(mto)3] (mto C 2O3S)

Abstract

In iron mixed-valence complex, (n-C3H7) 4N[FeIIFeIII(dto)3] (dto C 2O2S2), the linkage isomerisation and charge-transfer between FeII FeIII occur in the precipitation process. We succeeded the suppression of linkage-isomerization and charge-transfer in the formation process of (n-C3H7) 4N[FeIIFeIII(dto)3] by the synthesis on low temperature condition and the selection of solvent. Moreover, we have found that the charge transfer occurs in the formation of (n-C4H 9)4N[FeIIFeIII(mto)3] (mto C2O3S) without linkage-isomerization. © 2010 IOP Publishing Ltd.
