The novel lanthanide(III) complexes [Ln(NO(3))(2)L](NO(3))center dot 3MeOH (Ln = La 1, Pr 2) and [Ln(NO(3))(3)L](NO3)center dot 2MeOH (Ln = Gd 3, Yb 4), where L = (NE,N'E)-2,2'-(ethane-1,2-diylbis(oxy))bis(N-(pyridin-2-ylmethylene)ethanamine), have been obtained by direct reaction of the Schiff base ligand and the corresponding hydrated lanthanide(III) nitrates in methanol. All complexes were characterized spectroscopically and thermogravimetrically. Complex 4 was also characterized with crystallographic studies: orthorhombic P2(1)2(1)2(1), a = 10.6683(14), b = 13.4752(15), c = 19.3320(26) angstrom. In the molecular structure of 4, Yb(III) is surrounded by all donor atoms of the Schiff base (four nitrogen and two oxygen atoms) and four oxygen atoms belonging to two bidentate chelating nitrato ligands.
