Complex ions and ligands
Complex ions and ligands
Real World
Haemoglobin in your blood is a complex ion where Fe²⁺ is coordinated to a porphyrin ring and histidine ligands, with O₂ acting as a ligand during oxygen transport from lungs to tissues.
Exam Focus
Define a ligand as a species that donates a lone pair to the metal ion — simply saying 'bonds to' is insufficient.
