Organotin compounds คือ

Organosilicon chemistry is the science of the preparation and properties of organosilicon compounds, which are organometallic compounds containing carbon–silicon bonds. Most organosilicon compounds are similar to the ordinary organic compounds, being colourless, flammable, hydrophobic, and stable to air. Silicon carbide is an inorganic compound. WitrynaOrganotins are compounds consisting of one to four organic components attached to a tin atom via carbon–tin covalent bonds. When there are fewer than four carbon–tin bonds, the organotin cation can combine with an anion such as acetate, carbonate, chloride, fluoride, hydroxide, oxide, or sulfide.
