Abstract: The title complex, [Ni(C₁₈H₁₂N₂O₃)(C₅H₅N)], has a slightly distorted square-planar coordination of the Ni atom with trans N atoms [Ni-N = 1.902  (2) and 2.002  (2)  Å, Ni-O = 1.880  (2) and 1.927  (2)  Å, N-Ni-N = 171.30  (9)° and O-Ni-O = 173.87  (8)°]. The 2-hydroxybenzoyl hydroxy group forms an intramolecular O-HN hydrogen bond with an adjacent N atom [NO = 2.591  (3)  Å]. Inversion-related molecules have short NiN separations of 3.274  (3) and 3.489  (3)  Å, and exhibit concomitant - stacking; the centroid of the benzoyl ring is some 3.34  Å from the naphthalene plane of the inversion-related molecule.
