Coordination of the new tridentate N-heterocyclic carbene ligand precursor (p-Me-C₆H₄NHCH₂CH₂)₂N₂C₃H₂ to Zr(IV) generates an [NCN] donor setwhere the N represents an amido unit and the C corresponds to the N-heterocyclic carbene. This ancillaryligand allows for the isolation and structural characterization of zirconium amido, chloro, and alkyl derivatives; the carbene donor is rendered stable to dissociationbecause of its central disposition between two anionicamido units.
