Cyclopropanetrione or trioxocyclopropane is a little-known
oxide of carbon with formula C
3O
3. It consists of a ring of three carbon atoms each attached to an oxygen atom with a double bond. Alternately, it can be thought as a trimer of
carbon monoxide
Carbon monoxide (chemical formula CO) is a colorless, poisonous, odorless, tasteless, flammable gas that is slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simple ...
