Synthesis and spectroscopic characterization on the tri-iodide charge transfer complex resulted from the interaction between morpholine as donor and iodine sigma-acceptor

Charge-transfer (CT) complex formed between morpholine (Morp) as donor with iodine (1(2)) as acceptor has been studied spectrophotometrically. The synthesis and characterization of morpholine CT-complex of iodine, {[}(Morp)(2)]I(+.) I(3)(-) was described. This complex is readily prepared from the reaction of Morp with I(2) within CHCl(3) solvent. IR spectra, UV-Vis techniques and elemental analyses (C, H and N), characterize the Morph charge-transfer complex. Benesi-Hildebrand and its modification methods were applied to the determination of association constant (K), molar extinction coefficient (epsilon). (C) 2010 King Saud University.
