ABSTRACT

The charge-transfer complexes formed during the reactions of Coumarin 6 (Coum 6) as donors with َ-acceptors, like iodine and some ً-acceptors such as chloranilic acid (CLA) and picric acid (PA), have been investigated spectrophotometrically. The data obtained indicate the formation of the new CT-complexes with a general formula [(Coum 6)(acceptor)].

Keywords: Charge-transfer complexes; chloranilic; coumarin 6; iodine; picric acid; thermal studies.
