Two distinct coordination geometries are found in the binuclear title complex, [Ni(2)(C(13)H(19)N(2)O(2))(2)(N(3))(2)(CH(3)OH)], as one Schiff base ligand is penta­dentate, coordinating via the anti­cipated oxide O, imine N and amine N atoms (as for the second, tridentate, ligand) but the oxide O is bridging and coordination also occurs through the meth­oxy O atom. The Ni(II) atoms are linked by a μ(2)-oxide atom and one end of a μ(2)-azide ligand, forming an Ni(2)ON core. The coordination geometry for the Ni(II) atom coordinated by the tridentate ligand is completed by the meth­oxy O atom derived from the penta­dentate ligand, with the resulting N(3)O(3) donor set defining a fac octa­hedron. The second Ni(II) atom has its cis-octa­hedral N(4)O(2) coordination geometry completed by the imine N and amine N atoms of the penta­dentate Schiff base ligand, a terminally coordinated azide N and a methanol O atom. The arrangement is stabilized by an intra­molecular hydrogen bond between the methanol H and the oxide O atom. Linear supra­molecular chains along the a axis are formed in the crystal packing whereby two amine H atoms from different amine atoms hydrogen bond to the terminal N atom of the monodentate azide ligand.
