“…The observed planarity extends throughout dithiocarbamate fragments of the ligand backbones, thus showing evidence of delocalization of the π-electrons over the C-S and C-N bonds. This is also supported by the respective bond distances which imply partial double bond character for both C-S and C-N bonds and are similar to other dithiocarbamate complexes[9][10][11][13][14][15][16][17][18][19][20][21]. In the lack of functional groups that would influence in strong directional intermolecular binding, the solid state packing of 1 is seemingly governed by weak van der Waals interactions.…”

“…1 H, 13 C and 31 P NMR spectra were recorded on Bruker Avance 500 MHz spectrometer operating at 303K, using CDCl 3 as solvent. 13 C NMR spectra were recorded in proton decoupled mode. In 1 H and 13 C NMR runs the chemical shifts are referenced to the signal of the internal tetramethylsilane (TMS) and in 31 P NMR to the signal of the external 85 % orthophosphoric acid in a 1 mm diameter capillary tube inserted coaxially inside the 5 mm NMR-tube.…”

Nickel sulfide thin films and nanocrystals synthesized from nickel xanthate precursors

et al. 2017

Nickel sulfide thin films and nanocrystals stabilized with oleylamine ligands are prepared from two different nickel xanthates as single-source precursors, which decompose at approx. 180°C, and are thereby converted into nickel sulfide. These nickel xanthates comprise branched alkyl moieties allowing the choice of a wide range of nonpolar organic solvents for the processing to nickel sulfide thin films as well as to nanoparticles. The crystal structures of both compounds show a typical square-planar coordination of the sulfur atoms of both xanthates to the nickel central atom. The thermal decomposition via the Chugaev reaction forming nickel sulfide was studied by thermal gravimetric analysis showing the reaction taking place at about 180°C. Consequently, by thermally converting spin-coated metal xanthate films directly on the substrates in the solid state, thin films consisting of hexagonal nickel sulfide are formed. If the nickel xanthates are heated in an oleylamine solution, oleylaminecapped nickel sulfide nanocrystals are obtained, exhibiting hexagonal NiS as main phase and Ni 3 S 4 as secondary phase. This is also reflected in a sulfur-rich composition of the synthesized nickel sulfide nanocrystals as observed from TEM-EDX analyses.
