Transition metal carbyne complex

Transition metal carbyne complexes are organometallic compounds with a triple bond between carbon and the transition metal.[1] This triple bond consists of a σ-bond and two π-bonds.[2] The HOMO of the carbyne ligand interacts with the LUMO of the metal to create the σ-bond. The two π-bonds are formed when the two HOMO orbitals of the metal back-donate to the LUMO of the carbyne. They are also called metal alkylidynes—the carbon is a carbyne ligand. Such compounds are useful in organic synthesis of alkynes and nitriles. They have been the focus on much fundamental research.[3]
