Bis{2-[(E)-benzyl­imino­meth­yl]-4-methyl­phenolato-κ²N,O}nickel(II)

In the title complex, [Ni(C₁₅H₁₄NO)₂], the Ni^II atom is located on an inversion centre and is coordinated by two O and two N atoms from two symmetry-related bidentate Schiff base ligands in a slightly distorted square-planar geometry. The phenyl and benzene rings in the ligand mol­ecule form a dihedral angle of 72.79 (8)°.
