{μ-2-[(3-Amino-2,2-dimethyl­prop­yl)imino­meth­yl]-6-meth­oxy­phenolato-1:2κ5 O 1,O 6:N,N′,O 1}{2-[(3-amino-2,2-dimethyl­prop­yl)imino­meth­yl]-6-meth­oxy­phenolato-1κ3 N,N′,O 1}-μ-azido-1:2κ2 N:N-azido-2κN-methanol-2κO-dinickel(II)

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.
