Coordination compounds are metal atoms or ions holding a fixed set of ions or molecules through donated electron pairs. The chapter starts from Werner's experiments on cobalt-ammonia chlorides, sets out the vocabulary and IUPAC naming, classifies isomers, and explains bonding, magnetism and colour with valence bond and crystal field theory, before metal carbonyls and everyday uses in analysis, metallurgy, biology and medicine.
