The title complexes, (C15H15N2O3)xRE(NO3)y, when RE = La-Gd, x = 3, y = 6; and when RE = Tb-Lu, Y, x = 2, y = 5, were synthesized by the reaction of rare earth nitrate with 4-[2-(3-nitro-4-methoxyphenyl)vinyl]-1-methylpyridinium nitrate in anhydrous EtOH and were characterized by IR, UV and 1H NMR spectra, TG-DTA, molar conductance and x-ray powder diffraction. Factors affecting their composition are discussed.
