Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS 2 and structure S=C=S. It is also considered as the anhydride of thiocarbonic acid . [ 8 ] It is a colorless, flammable, neurotoxic liquid that is used as a building block in organic synthesis.
In disulfide, sulfur exists in the reduced state with oxidation number −1. Its electron configuration then resembles that of a chlorine atom. It thus tends to form a covalent bond with another S − center to form S 2− 2 group, similar to elemental chlorine existing as the diatomic Cl 2.
The largest man-made sources of carbonyl sulfide release include its primary use as a chemical intermediate and as a byproduct of carbon disulfide production; however, it is also released from automobiles and their tire wear, [9] coal-fired power plants, coking ovens, biomass combustion, fish processing, combustion of refuse and plastics ...
The handling of this chemical may incur notable safety precautions. It is highly recommended that you seek the Material Safety Datasheet for this chemical from a reliable source such as SIRI, and follow its direction.
The figure shows the six carbon atoms arranged at the vertices of a triangular prism with the tungsten at the centre. The hydrogen atoms are not shown. Some other transition metals have trigonal prismatic hexamethyl complexes, including both neutral molecules such as Mo(CH 3) 6 and Re(CH 3) 6 and ions such as Ta(CH 3) − 6 and Zr(CH 3) 2− 6. [3]
Carbon disulfide hydrolase is an enzyme with a molecular mass of 23,576 Da. The enzyme is hexadecameric. It catalyzes the hydrolysis of carbon disulfide. [1] Carbon disulfide occurs naturally in the mudpots of volcanic solfataras. It is a precursor to hydrogen sulfide, which is an electron donor.
The carbon atom lies at or near the apex of a square pyramid with the other four groups at the corners. [7] [8] The simplest examples of organic molecules displaying inverted tetrahedral geometry are the smallest propellanes, such as [1.1.1]propellane; or more generally the paddlanes, [9] and pyramidane ([3.3.3.3]fenestrane).
It arises from the reaction of aqueous base with carbon disulfide: CS 2 + 2 NaOH → Na 2 COS 2 + H 2 O. Important derivatives of dithiocarbonates are the xanthates (O-esters of dithiocarbonates), with the formula ROCS − 2. These salts are typically prepared by the reaction of sodium alkoxides with carbon disulfide.
