Abstract

Pyrolysis of trisbipyridineiron(II) chloride under controlled thermal conditions and inert atmosphere of argon gas yields a residue of iron nanoparticles. Evolved gas analysis by GC–MS and 1H NMR revealed emission of bipyridine, 6-chlorobipyridine, 6,6′-dichlorbipyridine, bipyridine hydrochloride, and hydrochloric acid as decomposition products. CHN, XRPD, EDXRF, TEM, AFM, and 57Fe Mössbauer spectroscopy of the residue indicated formation of pure iron nanoparticles in the size range of 50–72 nm. Based on these results a mechanism for thermal degradation of trisbipyridineiron(II) chloride has been worked out.
