ethylenediamine lewis structure

Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C2H4(NH2)2. 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. Contraindications & Blackbox Warnings data.
