Ligand exchange
Ligand exchange
When one ligand in a complex ion is replaced by another
Properties altered by ligand exchange
Properties altered by ligand exchange
Colour, coordination number, and geometry
Monodentate ligand
Monodentate ligand
Ligand binding through one atom
Bidentate ligand
Bidentate ligand
Ligand binding through two donor atoms
EDTA coordination type
EDTA coordination type
Hexadentate (coordinates through six donor atoms)
Effect of replacing
Effect of replacing
Coordination number often reduces from 6 to 4
Chelate effect
Chelate effect
Increased stability of bi/multidentate ligands compared to monodentate ligands
Entropy change in chelate effect
Entropy change in chelate effect
Increases disorder, favours chelate complex formation
