%X The asymmetric unit of the title compound, [Sm(NO3)3(C15H15NO2)2(CH3OH)], contains two Schiff base 2-methoxy-6-[(4-methylphenyl)iminiomethyl]phenolate (HL) ligands, three nitrate ions and one methanol molecule that binds to the nine-coordinate samarium(III) ion via its O atoms. The HL ligands chelate with a strong Sm！O(deprotonated phenolic) bond and a weak Sm！O(methoxy) contact. The latter can be interpreted as the apices of the bicapped square-antiprismatic SmIIIO9 polyhedron. The Schiff base ligands are in a zwitterionic state with the phenolic H atom transferred to the imine N atom. O！H...O, O！H...N and N！H...O hydrogen bonds lend stability to the structure. One O atom of one nitrate group is equally disordered over two positions.
