Abstract
Nine haloacetate complexes of Pr 3+ and Nd 3+ have been spectrophotometrically studied to study the structure of these complexes in solution state. The observed spectra in the visible region have been analyzed to calculate Slater-Condon, Landé, bonding and Judd-Ofelt intensity parameters. The degree of covalency in the bonding decreases in the order mono > di > tri halogen substituted complexes. In solution state the studied complexes are predominantly of ML species. All the complexes have nearly the same symmetry.
