22 of the 28 fundamental vibrations of both molecules have been identified and used to calculate force constants applying a modified Urey-Bradley force field with 9 independent constants. Favorite Answer. This compound upon standing is isomerised to a complex in which a nitrogen atom forms the additional bond to the metal centre. This endothermic enthalpy of formation originates in the difference in energy of S4N4 compared to its highly stable decomposition products: Because one of its decomposition products is a gas, S4N4 can be used as an explosive. [1] The bonding in S4N4 is considered to be delocalized, which is indicated by the fact that the bond distances between neighboring sulfur and nitrogen atoms are nearly identical.

Convert grams S4N4 to moles or moles S4N4 to grams. A related synthesis employs sulfur monochloride and NH4Cl instead:[1]. It can be viewed as a derivative of a hypothetical eight-membered ring of alternating sulfur and nitrogen atoms. Indeed, a large number of S-N and S-NH compounds are known with S4N4 as their parent. Molar Mass: 184.2868. GOPINATHAN AND WHITEHEAD: ELECTRONIC STRUCTURE OF S4N4 1345 TABLE 1.

In an apparently related reaction, the use of PPN+N3 gives a salt containing the blue [NS4]− anion:[10]. In the conversion, the silver first becomes sulfided, and the resulting Ag2S catalyzes the conversion of the S4N4 into the four-membered ring S2N2, which readily polymerizes.
