Sulfur chloride - Enkaiou

[ I ] Disulfur dichloride: S ₂ Cl ₂ (135.04). Usually, sulfur chloride refers to S ₂ Cl _2. It is obtained by reacting molten sulfur with chlorine. It is a fuming amber or yellow-red oily liquid. It has Cl-SS-Cl molecules, S-Cl 2.057 Å, S-S 1.931 Å. ∠SS-Cl 108.2°. The internal rotation angle is 85°. Its melting point is -80°C, its boiling point is 138°C. Its density is 1.69 g cm ^-3 . It is soluble in organic solvents such as alcohols, benzene, and carbon tetrachloride. It is hydrolyzed with water to produce S, SO ₂ , and HCl. It is used as a chlorinating agent in the manufacture of insecticides, dyes, synthetic rubber, etc. It is a toxic irritant that can cause damage to the skin, eyes, mucous membranes, etc. [CAS 10025-67-9] [ II ] Sulfur dichloride: _SCl2 (102.97). Obtained by reacting _{S2Cl2 with} chlorine. Dark red liquid with pungent odor. The gas molecule is a broken line Cl-S-Cl, S-Cl2.015 Å. ∠Cl-S-Cl102.7°. Melting point -122 °C, boiling point 59.6 °C. Density 1.62 g cm ^-3 . Soluble in hexane. Decomposes in water to _{produce H2S} , _SO2 , and _H2SO4 . Used as a solvent, chlorinating agent, rubber vulcanizer, insecticide, etc. Vapor is irritating to mucous membranes and is toxic. [CAS 10545-99-0] [ III ] Sulfur tetrachloride: _SCl4 (173.88). It is obtained by reacting _SCl2 with chlorine at -75°C. It is an unstable yellow crystal. Its structure is thought to be _SCl3 ^{+ Cl-} . It melts at -30°C and begins to decompose, becoming _SCl2 and _Cl2 . It is hydrolyzed with _water to become _SO2 and HCl. [CAS 13451-08-6] [ IV ] Polysulfane dichloride: _SnCl2 ( n _{= 3, > 3). SnCl2 is} obtained by reacting _SCl2 with excess _H2S or _H2Sn at -80°C. Its structure is thought to be Cl- _SSn -S- _Cl . _S3Cl2 is a yellow liquid. Melting point -46°C. Density 2.63 _g cm ^-3 _. Other known _species include _S4Cl2 and _S5Cl2 . [CAS 31703-09-0:S ₃ Cl ₂ ][CAS 15731-86-9:S ₄ Cl ₂ ][CAS 35380-30-4:S ₅ Cl ₂ ]
