Because oxygen and sulfur belong to the … WebGeneral structure of a thioether. A thioether is a molecule with the group R-S-R. The first atom in R is a carbon. Thioether take their name from ethers. They have a sulfur instead of an oxygen atom between the two R. Thioethers can have very bad smells like thiols. They can also be called sulfides. The C-S-C bond is at nearly 90 degrees.

Unlike ethers, thioethers occasionally serve as bridging ligands. The complexes Nb2Cl6(SMe2)3 is one such example. It adopts a face-sharing bioctahedral structure with a Nb(III)=Nb(III) bond, spanned by two chloride and one dimethylsulfide ligands. The complex Pt2Me4(μ-SMe2)2 is a source of "PtMe2". WebPolythiols also called polythioethers are compounds with mercaptane or thioether functions in the backbone. They are commonly prepared by reacting sodium sulfide with dichloro compounds: Polythiols can also be prepared by reacting dithiols with aldehydes or ketones.
