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