The distinction between the kinetics at low and high pH is in line with some mechanistic findings from earlier reports. WebEthylenediamine is a well-known bidentate chelating ligand for coordination compounds, with the two nitrogen atoms donating their lone pairs of electrons when ethylenediamine acts as a ligand. It is often abbreviated "en" in inorganic chemistry. The complex [Co (ethylenediamine) 3] 3+ is an archetypical chiral tris-chelate complex.
