Bis[2-(benzyl­amino)­pyridine-κN 1]bis­(2-formyl­phenolato-κ2 O,O′)nickel(II)

By Kouassi Ayikoé, Ray J. Butcher and Yilma Gultneh


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]
