Tin disulphide

Tin disulphide has the same dangerous reactions as sulphides, for which sulphide anion is very sensitive to the effect of oxidants. So the effect of chloric acid and chlorates gives rise respectively to violent detonations and the formation of spectacular showers of sparks. Dichlorine oxide detonates, but this is to be expected. 

EINECS 215-252-9 Mosaic gold Stannic sulfide Tin bronze Tin disulphide Tin sulfide (SnS2)tin disulfide . Used for gilding and bronzing metals and other surfaces. Golden leaflets d = 4.6, insoluble in H2O, soluble in alkali, aqua regia. 

The structure of barium tin disulphide, BaSnS2, is a distortion of the sodium chloride type. The space group is/ 2i/c with = 6.0848,6 = 12.1396, and c = 6.2356 A, and /3 = 97.058°. The structure can be considered as a composite of the BaS and SnS structures, both of which are based on the NaCl motif. Barium is in six-fold co-ordination in a slightly distorted octahedron of sulphur atoms. Tin is also enclosed octahedrally but is positioned close to a triangular face of S ions so that it is bonded to three S atoms only. In this polar arrangement Sn can be considered to have a tetrahedral environment in which a lone pair of electrons occupies one vertex. The cations are ordered so that Ba layers alternate with Sn layers in the overall NaCl-type architecture.

The reagent is prepared by dissolving 0-2 g 4-methyl-l, 2-dimercapto-benzene in 100 ml 1 per cent sodium hydroxide solution and adding 0-3-0-5 g thio-glycollic acid. The use of the latter in the reagent is not imperative, but it serves to facilitate the reduction of any tin(IV) ions present. The reagent is discarded if a white precipitate of the disulphide forms. 

Another form of iron disulphide occurs in nature as the mineral marcasitef which possesses a radiated structure and is frequently found as irregular balls on ehalky downs. When broken open the fracture exhibits a fibrous crystalline structure radiating from the centre—whence the name radiated pyrites. The fresh fracture is almost white m colour, and if quite pure the marcasite would probably be quite tin-white in appearance.7 When pure, its density at 25° C. is...

Organosulphur compounds represent the most common class of molecules exploited for formation of monolayers [1-8]. Many different kinds of similar molecules, e.g., aUcanethiols, dialkyl disulphides, dialkyl sulphides, thiophenes (Ths), thiophenols, and cysteines, have been reported to form monolayers on different substrates mainly consisting of (1) metals (e.g., Au, Ag, Cu, Pt, or Hg) or (2) semiconductors, such as indium tin oxide (ITO) and GaAs. Among the possible systems, the most extensively studied are those based on thiols adsorbed on Au. Although fundamental studies have also been carried out on the analogous Se and Te molecules, these have led to a limited number of applications in electroanalysis.
