Tricarbon (systematically named 1λ2,3λ2-propadiene and catena-tricarbon) is an inorganic compound with the chemical formula C
2(μ-C) (also written [C(μ-C)C] or C
3). It is a colourless gas that only persists in dilution or solution as an adduct. It is one of the simplest unsaturated carbenes. Tricarbon can be found in interstellar space and can be produced in the laboratory by a process called laser ablation.
