“…A number of reports suggest the use of Co(II) complexes [Co(S 2 CNR 2 ) 2 ] − as SSPs, although they are most likely the Co(III) complexes because square planar [Co(S 2 CNR 2 ) 2 ] are extremely oxygen sensitive and in organic solvents rapidly oxidize in air to [Co(S 2 CNR 2 ) 3 ] . Congiu and co-workers report that solid-state decomposition at 400 °C onto a fluoride-doped SnO 2 substrate gives CoS, subsequently tested as the counter electrode in dye-sensitized solar cell, while Zhu, Shen, and co-workers used [Co(S 2 CNEt 2 ) 2 ] to prepare Co 9 S 8 on the surface of graphene oxide via solvothermal decomposition in ethylene diamine at 180 °C for 24 h .…”

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.

“…77 Solvothermal decomposition of cobalt DTCs has not been widely studied. Thirumaran and co-workers decomposed furfuryl complexes [Co(S 2 CNR 2 ) 3 ] and [Co(S 2 CNRBz) 3 ] (R = CH 2 C 4 H 3 O) in triethylenetetramine to give nanorods of Co 3 S 4 , 78 while Revaprasadu and co-workers have reported that hot injection (HI) of [Co(S 2 CNC 8 H 8 O) 3 ] in oleylamine (OLA) affords nanoplates of CoS. 79 There are also reports of Co( ii ) complexes [Co(S 2 CNR 2 ) 2 ] 80–84 being used as SSPs, although as these are extremely oxygen sensitive, they are most likely to be the Co( iii ) complexes. 1 Most notably, ultra-thin, defect-rich, Co 9 S 8 nanosheets have been prepared by Li and co-workers from decomposition of (putative) [Co(S 2 CNBu 2 ) 2 ] at 220 °C in oleic acid in the presence of excess PPh 3 .…”

Bis(morpholinyl-4-carbodithioato)-platinum(II) was synthesized and characterized using spectroscopic techniques and single-crystal X-ray crystallography. The Pt(II) complex crystallized in a monoclinic space group P 2 1 / n with a Pt(II) ion located on an inversion center coordinated two morpholinyl dithiocarbamate ligands that are coplanar to form a slightly distorted square planar geometry around the Pt(II) ion. The complex was thermolyzed at 120, 180, and 240 °C to prepare PtS 2 nanoparticles. Powder X-ray diffraction patterns confirmed the hexagonal crystalline phase for the as-prepared PtS 2 nanoparticles irrespective of thermolysis temperature. Bead-like shaped PtS 2 - 120 nanoparticles with a particle size in the range of 12.46–64.97 nm were formed at 120 °C, while PtS 2 - 180 prepared at 180 °C is quasi-spherical in shape with particles in the range of 24.30–46.87 nm. The PtS 2 - 240 obtained at 240 °C is spherical with particles in the range of 11.45–46.85 nm. The broad emission maxima of the as-prepared PtS 2 nanoparticles are ascribed to the particles’ broad size distributions. The photocatalytic degradation of methylene blue by the PtS 2 nanoparticles shows a maximum efficiency of 87% for PtS 2 - 240 after 360 min. The effects of photocatalytic dosage, irradiation time, pH medium, and scavengers were also evaluated. Cyclic voltammetry of the PtS 2 nanoparticles showed a reversible redox reaction, while the electrochemistry of the as-prepared PtS 2 indicates that the electron transfer process is diffusion-controlled.
