A series of seven novel lanthanide(III) nitrato complexes with 4-[N-(2-methoxybenzylimine)formyl] 1-2, 3-dimethyl-1-phenyl-3-pyazolin-5-one (2mbfa), were synthesized. These complexes were characterized by elemental analysis, molecular mass determination, conductance and magnetic moment measurements, IR, UV-visible, and 13CNMR spectral studies. In these complexes, the Schiff base, 2mbfa, acts as neutral bidentate ligand by utilizing the carbonyl oxygen and azomethine nitrogen as donor sites. All the three nitrate ions are also coordinated unidentately with 7 coordination for the lanthanide(III) ions with a tentative monocapped octahedral geometry for the complexes. All the seven lanthanide(III) complexes have a general formula, [Ln(2mbfa)2(NO3)3].
