Bis[2-(benzyl-amino)-pyridine-?N]bis-(2-formyl-phenolato-?O,O')nickel(II).

ABSTRACT: In the title complex, [Ni(C(7)H(5)O(2))(2)(C(12)H(12)N(2))(2)], the Ni(II) atom lies on a center of inversion and is coordinated in an octa-hedral geometry by two 2-(benzyl-amino)-pyridine (2-BAP) and two 2-formyl-phenolate ligands with the O-atom donors in the equatorial plane and the pyridine N atoms in axial positions. There are hydrogen-bonding inter-actions between the secondary amine H atom and the phenolate O atom, as well as C-H?O inter-actions, which result in the dihedral angle between the aromatic phenyl ring of the 2-formyl-phenolate moiety and the pyridine ring being 80.23?(4)°. In the packing, there are both C-H?? inter-actions, which link the mol-ecules into chains along the b axis, and offset ?-? inter-actions 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].
