Chemical and spectroscopic studies in metal β-diketonates. IX. A novel intermolecular charge-transfer system involving metal acetylacetonate (donor) and iodine (acceptor)

Abstract

A spectrophotometric study of 1 : 1 charge-transfer complexes derived from five metal acetylacetonates (donor) and iodine (acceptor) has been carried out. Iomzation potential of each metal acetylacetonate and the equilibrium constants for the formation of the chelate-iodine complex have been evaluated. The plot of ionization potential of donors against hv_Ct values gave a straight line.
