LIGAND TYPES
• A potential ligand must have an atom
with an unshared pair
of electrons suitable for bond formation with the central metal ion.
• The donor
atoms in the ligand are those with available
electron density
ie. the more electronegative elements, on the right hand side of the Periodic Table.
ie. the more electronegative elements, on the right hand side of the Periodic Table.
• A ligand may be neutral (e.g. the ammonia molecule, NH3) or charged (e.g. the chloride ion, Cl-).
