Some light-lanthanide nitrate complexes were obtained by the reaction of lanthanide nitrate with isonicotinoyl hydrazone (HL＝N,N′-diisonicotinoyl-2-hydroxy-5-methyl-isophthalaldehyde dihydrazone) in methanol. The general formula of the complexes is Ln(L)(NO3)2*nH2O(Ln＝La, Ce, Pr, Nd and Sm; n＝0, 1). The complexes were characterized by elemental analyses, conductance, thermal analyses, UV and IR spectra. The results show that the lanthanide ion in each complex is coordinated by oxygen and nitrogen atoms of the ligand (L) and the oxygen atoms of the nitrate. The amide-oxygen atoms of L coordinate to the Ln ions in its keto-form. The magnetic susceptibility of the neodymium complex shows that the magnetic data obey Curie-Weiss law in the range of 75K＜T＜300K.
