Phase pure SnS nanosheets were synthesized by a hot injection method from a new single molecular precursor (SMP), dibutyl-bis(piperidinedithiocarbamato)tin(iv) in oleylamine at 230 degrees C. The tin complex was characterized by single crystal X-ray crystallography, nuclear magnetic resonance, thermogravimetry and microelemental analysis. The complex is thermally stable up to 260 degrees C, after which it decomposes in a single step with a major mass loss between 260 degrees C and 300 degrees C. The thermolysis of the as-prepared precursor was carried out in oleylamine between 190 and 230 degrees C. The formation and shape evolution of SnS was investigated using high resolution electron microscopy. The mechanism of the time dependent growth of SnS from spherical particles into nanosheets is proposed.
