Diiron hexakis(carbonyl) (µ-disulfide) Fe2(CO)6(μ-S2) was synthesized and charcacterized. Pyrolysis of Fe2(CO)6(μ-S2) at temperature <500°C produced Fe1−xS or Fe7S8 powders, according to powder XRD spectra, whereas at higher temperature 750 °C polycrystalline FeS powder was obtained.
Diiron hexakis(carbonyl) (µ-disulfide) Fe2(CO)6(μ-S2) was applied as a single source precursor for the growth of FeS film via MOCVD.
Polycrystalline Fe1−xS or Fe7S8 films were obtained on Si(100) and Ag–Si(100) substrates below 500 °C. Whisker-like grains where present in the film grown on Si(100) substrates,
according to SEM micrographs. However, on Ag–Si(100) substrates pillar-like grains were obtained. Growth rates were different for different substrates (determined from layer thickness by cross-sectional SEM). At 750 °C, similar polycrystalline Fe1−xS
or Fe7S8 film was obtained.[[i]]
