In the centrosymmetric tetra­nuclear title complex, [Ni4(C12H15NO3)2(CH3COO)2(N3)2(CH3OH)2]·2CH3OH, the asymmetric unit comprises half of a complex mol­ecule and a methanol solvent mol­ecule. The NiII ions display two different coordination environments: (i) two O atoms from the Schiff base ligand, two O atoms from symmetry-related methanol mol­ecules and an O atom from an acetate group, one N atom from the azide group, and (ii) two O atoms and one N atom from the Schiff base, one O atom from methanol, one O atom from the acetate anion, and one N atom from the azide group. Four coplanar NiII ions are connected by two μ2-bridging O atoms from the two deprotonated Schiff bases, two μ3-O atoms from methanol mol­ecules, two μ1,1-N atoms from two azide ions, and four O atoms from acetate groups. The shortest Ni...Ni distance in the tetra­nuclear unit is 2.962 (2) Å. O—H...O hydrogen bonds between the methanol solvent mol­ecule and an acetate O atom feature in the crystal packing.
