## Abstract A novel chelating chiral bis(formamidineβurea) ligand was synthesized and used to prepare the corresponding Ni^II^ and Cu^II^ complexes. Spectroscopic and Xβray crystallographic analysis of the former revealed that the urea moiety of the acyclic tetradentate ligand is deprotonated and b
