'''Thioxoethenylidene''' is a chemical compound with the formula C2S. It is a member of the [[carbene]] family, which are organic compounds that contain a carbon atom with only six electrons in its outer shell, making it a highly reactive species. Thioxoethenylidene is unique among carbenes for its incorporation of a sulfur atom, which imparts distinctive chemical properties.
