ABSTRACT:
The reactions between 2,2 bipyridine (Bpy) and hydroxy benzo pyridine (8HQ) as electron donors with some acceptors such as chloranilic acid (CAA), 3, 5 di nitro benzoic acid (DNBA) and p-nitro phenol (PNP) were studied at room temperature. Based on FT- IR spectrum of the solid CT complexes along with the UV- visible spectroscopy for the reactions, the data obtained indicate the formation of 1:1 charge-transfer complexes. The infrared and 1H NMR spectroscopic data and XRD spectrum indicate a charge-transfer interaction associated with a proton migration from the acceptor to the donor followed by intermolecular hydrogen bonding.
KEYWORDS:
