Unsaturated metal centres creation upon activation acts as Lewis acid sites and ethylenediamine with a strong basic character in the structure remarkably facilitate an efficient and economic strategy for better organic transformations. Bidentate ligands are Lewis bases that donate two pairs ("bi") of electrons to a metal atom.. Bidentate ligands are often referred to as chelating ligands ("chelate" is derived from the Greek word for "claw") because they can "grab" a metal atom in two places.. A complex that contains a chelating ligand is called a chelate. Coordination Complexes. 2,2',2'',2'''- (ethane-1,2-diyldiazaniumyl)tetraacetate.
