Biomarkers charge-transfer complexes of melamine with quinol and picric acid: Synthesis, spectroscopic, thermal, kinetic and biological studies

Two new melamine (MA) charge transfer complexes with quinol and picric acid in aqua media have been synthesized and structurally characterized. The obtained complexes with the general formula [(MA)(acceptor)(2)] with a 2:1 acceptor:donor molar ratio. Elemental analysis (CHN), electronic spectra, photometric titration, mid infrared spectra, H-1 NMR spectra and thermogravimetric analysis (TG) were used to predict the position of the charge transfer interaction between the donating and accepting sites. The MA CT-complexes were antimicrobial assessment against two kinds of bacterial and fungal species. (C) 2014 King Saud University. Production and hosting by Elsevier B.V.
