Paper Title:
Synthesis, Spectral Properties of Methyl-2-Pyridyl Ketone Benzoyl Hydrazone and its Complexes with Rare Earth Nitrates
  Abstract

A new schiffbase ligand, methyl-2-pyridyl ketone benzoyl hydrazone (L), and its complexes with rare earth nitrates have been synthesized. These new complexes with the general formula of Ln(L)2(NO3)3·nH2O(where Ln = La, n = 5.5; Ce, Pr, n = 5; Nd, Eu, n = 4 ) were characterized by mass spectra, elemental analysis, IR spectra, thermal analysis, UV spectra, molar conductivity and luminescent spectra. All the complexes are stable in air. The results show that the lanthanide ion in each complex are coordinated by oxygen and nitrogen atoms of the ligand, the oxygen atoms of the nitrate and coordinated water molecules. The amide-oxygen atoms of L coordinate to the Ln ions in its keto-form. Tentative structures for the complexes have been proposed.
