Abstract
Synthesis, characterization and spectroscopic studies of Iron (III) and Copper(II) complexes ofa-hydroxyl phosphonate
Author(s): Dalila Fedaoui, Abdeslem Bouzina, Nour-Eddine Aouf, Yacine Bouhadja and Malika BerredjemPrevious studies show that the phosphate groups play a role important in the complexation process as a whole more effective donor that carboxylate groups. The presence of the aromatic ring increases the power complexing of these molecules. We present here a spectrophotometric method for the determination of two complex [M(L1)nH2O] L1 = dimethyl (hydroxy(phenyl)methyl)phosphonate and [M(L2)nH2O] L2 = diethyl (hydroxyl (phenyl)methyl) phosphonate, the procedure is based on the chelation of the ligand with Fe (III) to formred complex and Cu (II) to form yellow complex at room temperature which absorbs maximally at 405 nm and 308 nm and Beer’s law is obeyed over the concentration range of 2-27mg/ml. The IR spectroscopy revealed that iron and copper ions coordinated through phosphonyl (P=O) and hydroxyl group (O-H) of the a-hydroxyl phosphonate.
