A STUDY ON PREPARATION AND HYPERSENSITIVE TRANSITION PHENOMENON OF THE LANTHANIDES (Nd3+, Ho3+, Er3+)—1-PHENYL-3-METHYL-4-BENZOYL-PYRAZOLONE-5—8-HYDROXYQUINOLINE TERNARY COMPLEXES

The lanthanides (Nd3+,Ho3+.,Er3+) complexes with 1-phenyl-3-methyl-4-ben-zoyl-pyrazolone-5 (Hpmbp) and 8-hydroxyquinoline (Ox) in ethanolic solution have been studied by spectrophotometry.The ethanolic solution spectra of Ln3+ (Nd,Ho,Er) nitrates,β-diketonate (Hpmbp) chelates and Ln3+-Hpmbp-Ox ternary complexes show the change of absorption bands of hypersensitive transition and the corresponding incroaso of absorbance.Using the methods of continuous-variation and equilibriumshift,wo havo shown that in the ternary complexes formed,the ratio of components is Ln3+:Hpmbp:Ox-1:3:2.
