Abstract
Cyclooligomerisation of the amino acid thiazole 3 is influenced by metal io ns, with smaller alkali metal ions favouring the formation of the trimer 4, and larger metal ions (eg Cd2+) enhancing the formation of the tetramer 5. A crystalline complex obtained be tween the tetramer 5 and Ag BF4 is shown by X-ray studies to comprise two macrocycles and five silver ions in a 'sa ndwich' type arrangement.
