New zirconium and zirconocene guanidinate complexes

► The X-ray structure of a lithium monoanionic guanidinate compound is reported. ► Change in the coordination modes of guanidinate complexes in solution is proposed. ► Evolution should be explained by a decoordination and intermolecular interaction. ► Fluxional behavior was studied for the guanidinate zirconocene complexes.
