Abstract

In the title complex, [Ni(C7H5O2)2(C12H12N2)2], the NiII atom lies on a center of inversion and is coordinated in an octahedral geometry by two 2-(benzylamino)pyridine (2-BAP) and two 2-formylphenolate ligands with the O-atom donors in the equatorial plane and the pyridine N atoms in axial positions. There are hydrogen-bonding interactions between the secondary amine H atom and the phenolate O atom, as well as C—H⋯O interactions, which result in the dihedral angle between the aromatic phenyl ring of the 2-formylphenolate moiety and the pyridine ring being 80.23 (4)°. In the packing, there are both C—H⋯π interactions, which link the molecules into chains along the b axis, and offset π–π interactions involving both the pyridine and phenyl rings of the 2-BAP ligands [centroid–centroid distances = 4.0100 (8) Å for the pyridine rings and 3.6601 (8) and 4.8561 (8) Å for the phenyl rings].
