Ethylenediamine protonated
WebEthylenediamine (en) is a bidentate ligand that forms a five-membered ring in coordinating to a metal ion M Polydentate Ligands Polydentate ligands range in the number of atoms used to bond to a central metal atom or ion. The compound is prepared from an aqueous solution of ethylenediamine and virtually any cobalt(II) salt, such as cobalt(II) chloride. The solution is purged with air to oxidize the cobalt(II)-ethylenediamine complexes to cobalt(III). The reaction proceeds in 95% yield, and the trication can be isolated with a variety of anions. A detailed product analysis of a large-scale synthesis revealed that one minor by-product was [Co(en)2Cl(H2NCH2CH2NH3)]Cl3, which contains a ra…
