Abstract
It is demonstrated that complexation between the ferric cation and the Z-ch alcone of the naturally occurring anthocyanin malvin takes place in acidic aqueous solutions. The flexible open cavity of the Z-chalcone best fits the steric and electronic requirements of the ferric ion in water. (C) 1999 Pu blished by Elsevier Science Ltd. All rights reserved.
