Di-μ(2)-acetato-di-μ(2)-azido-di-μ(3)-methanol-tetra-kis-{μ-2-[(2-methyl-1-oxidopropan-2-yl)imino-meth-yl]-6-meth-oxy-phenolato}tetra-nickel(II) methanol disolvate.

In the centrosymmetric tetra-nuclear title complex, [Ni(4)(C(12)H(15)NO(3))(2)(CH(3)COO)(2)(N(3))(2)(CH(3)OH)(2)]·2CH(3)OH, the asymmetric unit comprises half of a complex mol-ecule and a methanol solvent mol-ecule. The Ni(II) ions display two different coordination environments: (i) two O atoms from the Schiff base ligand, two O atoms from symmetry-related methanol mol-ecules 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 Ni(II) ions are connected by two μ(2)-bridging O atoms from the two deprotonated Schiff bases, two μ(3)-O atoms from methanol mol-ecules, two μ(1,1)-N atoms from two azide ions, and four O atoms from acetate groups. The shortest Ni⋯Ni distance in the tetra-nuclear unit is 2.962 (2) Å. O-H⋯O hydrogen bonds between the methanol solvent mol-ecule and an acetate O atom feature in the crystal packing.
