Tetrasulfur tetranitride (SN) was treated with various alkyl aryl ketoximes having two hydrogens at the α-carbon atom to the oxime functionality in -dioxane at reflux to give 3-substituted and 3,4-disubstituted 1,2,5-thiadiazoles in moderate yields.

It can be made by reacting disulfur dichloride with ammonia. On heating, these thiazyl chlorides 6S2Cl2 + 16NH3 -> S4N4 + S8 + 12NH4Cl Tetrasulfur tetranitride forms thermochromic crystals, which are crystals that change colour with temperature. reaction of the halogens with tetrasulfur tetranitride. Previous. Molar mass of S4N4 = 184.2868 g/mol Convert grams Tetrasulfur Tetranitride to moles or moles Tetrasulfur Tetranitride to grams. Tetrasulfur tetranitride is an inorganic compound with the formula S 4 N 4.This gold-poppy coloured solid is the most important binary sulfur nitride, which are compounds that contain only the elements sulfur and nitrogen.It is a precursor to many S-N compounds and has attracted wide interest for its unusual structure and bonding. Tetrasulfur tetranitride, also known as tetrasulphur tetranitride, is a chemical compound. Properties. The reaction of [Pt2Cl4(PMe2Ph)2] with S4N4 is reported to form a complex where a sulfur forms a dative bond to the metal, this compound upon standing is isomerised to a complex in which a nitrogen atom forms the additional bond to the metal centre. Thumbnails Document Outline Attachments. Many important S-N compounds are prepared from S4N4. Jump to navigation Jump to search. Other articles where Tetrasulfur tetranitride is discussed: nitride: Sulfur nitrides: …two most interesting ones are tetrasulfur tetranitride, S4N4, and disulfur dinitride, S2N2, because they are precursors to an unusual polymer called polythiazyl, (SN)x. 2K(s) + Br 2 2KBr(s) III. S4N4 is stable to endothermic heat of formation anticipates its inherent instability, and originates in the difference in energy of S4N4 compared to its highly stable decomposition products: It is not really very unusual for complex molecules to be unstable in a thermodynamic sense yet stable kinetically; this situation describes many compounds. Synthesis of tetrasulfur tetranitride (S 4 N 4) CCl 4 (250 mL) and S 2 Cl 2 (40 mL, 0.5 mol) were added to a 500 mL three-necked flask at 0 °C with stirring. Reaction with isobutyrophenone oxime under the same conditions did tetranitride: …(pl. S4N4 is sensitive to NaOH hydrolyzes S4N4 as follows:[1]. The pairs of sulfur atoms across the ring are further bonded, resulting in a cage-like structure with pentagonal S3N2 rings. Read "ChemInform Abstract: Reactions of Tetrasulfur Tetranitride with Tropolone and Its Several Halogen Derivatives. It can be viewed as a derivative of a hypothetical eight-membered ring of alternating sulfur and nitrogen atoms. Safety.
