Dimetallocenes are a narrow class of compounds represented by the homobimetallic examples dizincocene and diberyllocene. Now a heterobimetallic dimetallocene featuring lithium and aluminium centres has been synthesized. The Al–Li bond is shown to cleave upon reaction with N-heterocyclic carbenes and heteroallenes.
