In the title complex, [NiSm(C₁₉H₂₀N₂O₄)(NO₃)₃(CH₄O)₂]·2CH₃OH, the Ni^II ion is coordinated by two O atoms and two N atoms of a deprotonated Schiff base ligand and by two O atoms of two methanol ligands in a slightly distorted octahedral geometry. The Sm^III ion is coordinated by six O atoms from three chelating nitrate ligands and four O atoms from a Schiff base ligand in a distorted bicapped square-antiprismatic environment. In the crystal structure, intermolecular O-HO hydrogen bonds connect complex molecules and methanol solvent molecules, forming (10 $[\overline{2}]$ ) sheets.
