“…2). A similar square-planar arrangement was, for example, also found for other nickel alkyl xanthates [39,69]. In both compounds, the S-C bond lengths are nearly the same, expressing the bidentate nature of the S 2 CORR' ligands (Table 2).…”

“…Numerous single-source precursor compounds, which already contain a nickel sulfur bond, such as nickel dithiocarbamate [28][29][30][31][32][33][34], dithiocarbonate (xanthate) [35][36][37][38][39][40], thiolate [10,41], dithiooxamide [42], thiourea [43], thiobenzoate [44], thiobiuret [45], mercaptobenzothiazole [46], thiosemicarbazide [47], polysulfide [48], imidodiphosphinate [49] or dithiophosphate [50], have already been investigated for the fabrication of various nickel sulfide nanostructures.…”

“…The attractive properties of metal xanthates, like their usually good stability (also in solution), relatively low decomposition temperature (below 200°C) and simplicity to tailor solubility and decomposition behavior by variation of their organic side chains, have ensured that they are widely employed in the preparation of various metal sulfide nanomaterials [35][36][37][38][39][51][52][53][54][55][56][57][58][59][60].…”

“…A variety of binary (Bi 2 S 3 [52,61], CdS [53], CuS [36], HgS [36], MnS [36], ZnS [36], PbS [60], PdS [35], SnS [59], NiS [35][36][37][38][39]), ternary (copper indium sulfide [51], copper antimony sulfide [54]) and quaternary (copper zinc tin sulfide [55]) metal sulfide nanomaterials have already been synthesized via a thermally induced decomposition of the metal xanthates, proceeding via the Chugaev elimination mechanism [36,51]. Far less explored is the conversion of metal xanthates to metal sulfides at room temperature by photochemically induced decomposition using UV irradiation [56,57] or direct chemical reaction with primary amines.…”

“…Considering the attractive potential of metal xanthates as SSPs for the production of metal sulfide nanomaterials, it is surprising that there are only a few reports dealing with the thermal conversion of nickel xanthate complexes [35][36][37][38][39]. Therefore, in this contribution we demonstrate the potential of the two novel nickel xanthate precursors, nickel (II) O-3,3-dimethylbutan-2-yl dithiocarbonate (NiXa-C6) and nickel (II) O-2,2-dimethylpentan-3-yl dithiocarbonate (NiXa-C7), as SSP for the preparation of nickel sulfide nanostructures.…”

Nickel sulfide thin films and nanocrystals synthesized from nickel xanthate precursors

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.

Linear and branched zinc(II) xanthates with varying alkyl chain length were synthesized and characterized by 1H NMR, 13C NMR, and IR spectroscopy, as well as elemental analysis. Zinc sulfide as the final decomposition product upon thermal annealing of zinc(II) xanthates was confirmed by XRD analysis. Cure time for epoxy resin composite at various temperatures was analyzed employing zinc(II) xanthates (5 % mass) as latent cure catalysts. XRD investigation of the cured epoxy resin including zinc(II) xanthates upon thermal annealing revealed the presence of ZnS in‐situ in the composite matrix, indicating the in‐situ thermal decomposition of zinc(II) xanthates as probable mechanism for curing. Thermogravimetric analysis was performed to investigate the thermal decomposition temperature trend of zinc(II) xanthates. A parallel trend was observed correlating the thermal decomposition temperature trend of zinc(II) xanthates and the order of curing catalytic efficiency utilizing zinc(II) xanthates. In the case of linear alkylzinc(II) xanthates with an increase in the alkyl chain length, both thermal decomposition temperature and the cure time were enhanced. In contrast, in case of branched alkyl chain zinc(II) xanthates with increasing alkyl chain length show decreasing thermal decomposition temperature as well as cure time.
