Abstract:A systematic theoretical DFT study of the bonding between the cation Fe3+ and the anion View the MathML source was carried out. The role of water ligands is presented. Several isomers with tetrahedral, bipyramidal and octahedral environments around the iron ion were investigated. 5-fold coordination of the Fe3+ cation is found when 5 and 6 water molecules are included. Calculated infrared spectra are also presented.
Keywords:DFT/B3LYP   Phosphate   Iron (III) complexes   5-Fold coordination   Infrared spectra
