The addition of Cl 2 to S 2 Cl 2 has been proposed to proceed via a mixed valence intermediate Cl 3 S−SCl. SCl 2 undergoes even further chlorination to give SCl 4, but this species is unstable at near room temperature. It is likely that several S n Cl 2 exist where n > 2. Disulfur dichloride, S 2 Cl 2, is the most common impurity in SCl 2.
S 8 + 4 Cl 2 → 4 S 2 Cl 2, ΔH = −58.2 kJ/mol. Excess chlorine produces sulfur dichloride, which causes the liquid to become less yellow and more orange-red: S 2 Cl 2 + Cl 2 ⇌ 2 SCl 2, ΔH = −40.6 kJ/mol. The reaction is reversible, and upon standing, SCl 2 releases chlorine to revert to the disulfur dichloride.
Disulfur is the diatomic molecule with the formula S 2. [2] It is analogous to the dioxygen molecule but rarely occurs at room temperature. This violet gas is the dominant species in hot sulfur vapors.

One can subdivide chemical compounds into two main groups: molecules, which includes most organic, polyatomic gases, and organometallic compounds, and nonmolecular species, which includes most purely inorganic compounds. The structures of many reagents are often misunderstood because simplified formulas are presented in reaction schemes whereas ...
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
For a diatomic molecule, an MO diagram effectively shows the energetics of the bond between the two atoms, whose AO unbonded energies are shown on the sides. For simple polyatomic molecules with a "central atom" such as methane (CH 4) or carbon dioxide (CO 2), a MO diagram may show one of the identical bonds to the central atom. For other ...
These allotropes have been synthesised by various methods for example, treating titanocene pentasulfide and a dichlorosulfane of suitable sulfur chain length, S n−5 Cl 2: [17] (η 5-C 5 H 5) 2 TiS 5 + S n−5 Cl 2 → cyclo-S n + (η 5-C 5 H 5) 2 TiCl 2. or alternatively treating a dichlorosulfane, S n−m Cl 2 and a polysulfane, H 2 S m: [17 ...
