Lithium zirconimidate complexes (see structure) were isolated by deprotonation of zirconium methyl amide complexes or by addition of methyllithium across imidozirconium complexes. Quantitative studies on the acidity of these conjugate bases of zirconium amide complexes showed that both the kinetics and thermodynamics of proton exchange are influenced by the ancillary ligands on the zirconium center.
