Nanocrystalline iron oxide and sulfide by the thermal decomposition of cyclohexylammonium hexaisothiocyanatoferrate(III) 2.5H₂O.

ABSTRACT: We reported for the first time the establishment of a simple, room-temperature synthesis protocol for the new organic-inorganic hybrid salt of cyclohexylammonium hexaisothiocyanatoferrate(III) 2.5H₂O, which was found a convenient single-source precursor for the synthesis of nanocrystalline iron oxide or sulfide. The formation of this salt was spectrophotometrically confirmed by FT-IR and UV-Vis. In addition, SCXRD revealed that this salt had the trigonal space group R-3 with disorder of some isothiocyanate sulfur atoms. The thermal stability and the thermal decomposition products of this salt were atmosphere-dependent (air: 169 °C; α-Fe₂O₃ at 550 °C; helium: 154 °C; FeS at 800 °C). The thermal decomposition impacted the textural properties of α-Fe₂
