S4N4 is thermochromic, changing from pale yellow below −30 °C to orange at room temperature to deep red above 100 °C. Molar Mass: 184.2868. Lv 7. An examples of this is: Also contained in this group (D n group) is: D 3 D 4 D 5 D 6 D 7 D 8 n group) is: D 3 D 4 D 5 D 6 D 7 D 8 The symmetric group or , also termed the symmetric group of degree four, is defined in the following equivalent ways: 1. It is formed in a variety of chemical reactions involving sulfur and nitrogen and it can be utilized as a convenient reagent in the synthesis of other sulfur-nitrogen species. In particular, it is a symmetric group of prime power degree. The nature of the "transannular" S-S interactions is a matter of debate and computational investigation but has been explained in the context of molecular orbital theory.

GOPINATHAN AND WHITEHEAD: ELECTRONIC STRUCTURE OF S4N4 1345 TABLE 1. It is, however, unstable in the thermodynamic sense with a positive enthalpy of formation of +460 kJ mol−1. The [((CH3)3Si)2N]2S reacts with the combination of SCl2 and SO2Cl2 to form S4N4, trimethylsilyl chloride, and sulfur dioxide:[8], S4N4 serves as a Lewis base by binding through nitrogen to strongly Lewis acidic compounds such as SbCl5 and SO3. 1. [2][9] S4N4 reacts with Vaska's complex ([Ir(Cl)(CO)(PPh3)2] in an oxidative addition reaction to form a six coordinate iridium complex where the S4N4 binds through two sulfur atoms and one nitrogen atom. 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. Purer samples are more shock-sensitive than those contaminated with elemental sulfur. Chlorination of S4N4 gives thiazyl chloride. Small samples can be detonated by striking with a hammer. The periodic table has all of the information needed to draw a Lewis dot structure.
