Abstract: Anew ligand 1, 2-bis (1'-phenyl-3'-methyl-5'-oxopyrazol-4'-yl)-1, 2-phthaldione (H2L) and its rare earth complexes were prepared by the reaction of H2L with relative metal nitrate in aqueous solution. The binuclear structures of the complexes are proposed according to the elementary analysis results, molar conductance, IRand 1H NMRspectra.
