Identify examples of chelated ligands

  • Ligands are classified according to the manner in which they bind to the central metal ion
  • Ligands that bond using the electron pair of a single donor atom
    • Monodentate Ligands (One toothed)
    • g H2O, Cl, CN

  • Ligands that bond through electron pairs on more than one donor atom
    • Polydentate Ligands
  • Polydentate ligands are also known as chelating (Claw) agents
    • Multi-point attachment resembles a crab claw
    • Donor atoms bond simultaneously to the central metal ion
    • g oxalate ion, Ethylenediamine
