Abstract: A novel ligand 2,6-bis (1′- phenyl-3′-methyl-5′- oxo-4′-formylpyrazol)pyridine(H2L)and its complexes have been prepared by reacting H2L with rare earth nitrate in ethyl alcohol solution. The complexes have been characterized by elemental analysis,thermoanal-ysis,molar conductivity,IR,UV,1H NMR and fluorescence spectra measurements.
