The novel lanthanide(III) complexes[Ln(NO3)2L](NO3)⋅3MeOH (Ln = La1, Pr2) and[Ln(NO3)3L](NO3)⋅2MeOH (Ln = Gd3, Yb4), 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. Complex4was also characterized with crystallographic studies: orthorhombic P212121,a=10.6683(14),b=13.4752(15),c=19.3320(26) Å. In the molecular structure of4, 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.
