“…118 These promising early findings have not been developed, although a 2012 paper briefly reported that [Cr(S 2 CNH 2 ) 3 ] decomposes above 215 °C, with PXRD showing the strongest reflections for rhombohedral Cr 2 S 3 , together with several additional reflections possibly originating from comparatively deficient sulfur phases. 119…”

“…In 2000, Almond and co-workers reported that decomposition of [Cr(S 2 CNEt 2 ) 3 ] between 255 and 450 °C in a low-pressure flow reactor gave layers of Cr 2 S 3 in either rhombohedral or trigonal forms .

Nanodimensional metal sulfides are a developing class of low-cost materials with potential applications in areas as wide-ranging as energy storage, electrocatalysis, and imaging. An attractive synthetic strategy, which allows careful control over stoichiometry, is the single source precursor (SSP) approach in which well-defined molecular species containing preformed metal–sulfur bonds are heated to decomposition, either in the vapor or solution phase, resulting in facile loss of organics and formation of nanodimensional metal sulfides. By careful control of the precursor, the decomposition environment and addition of surfactants, this approach affords a range of nanocrystalline materials from a library of precursors. Dithiocarbamates (DTCs) are monoanionic chelating ligands that have been known for over a century and find applications in agriculture, medicine, and materials science. They are easily prepared from nontoxic secondary and primary amines and form stable complexes with all elements. Since pioneering work in the late 1980s, the use of DTC complexes as SSPs to a wide range of binary, ternary, and multinary sulfides has been extensively documented. This review maps these developments, from the formation of thin films, often comprised of embedded nanocrystals, to quantum dots coated with organic ligands or shelled by other metal sulfides that show high photoluminescence quantum yields, and a range of other nanomaterials in which both the phase and morphology of the nanocrystals can be engineered, allowing fine-tuning of technologically important physical properties, thus opening up a myriad of potential applications.
