Metallacumulenes and carbide complexes exhibit diverse structures and modes of reactivity. This review presents an overview of work in the author's research group on vinylidene complexes of group 6 and 8 metals, allenylidene and butatrienylidene complexes of group 8 metals, and metal carbide, bicarbide and tricarbide complexes of group 6, 7 and 8 metals.
