Thermal degradation of a molecular magnetic material: {N(n-C4H9)4[FeIIFeIII(C2O4)3]}∞

Abstract

Thermal degradation of a mixed-valence oxalate based molecular material {N(n-C4H9)4[FeIIFeIII(C2O4)3]}∞ was investigated by thermogravimetric (TG) analysis. Considering the mass loss at each step of TG profile, possible step-wise thermal degradation reaction pathways of the precursor material are proposed which indicate the formation of hematite and magnetite as the solid end product of the degradation reaction. The IR spectroscopy and powder X-ray diffraction (XRD) studies of the thermally degraded samples supplement the proposed reaction pathways.
