In the title complex, [Ni(C 14 H 11 N 3 OS)(C 5 H 5 N)], the Ni II atom is N,O,S-chelated by the deprotonated salicylaldimine-4phenylthiosemicarbazide dianion and is also coordinated by a pyridine molecule, the coordinating atoms giving rise to a square-planar geometry for the Ni atom. The asymmetric unit contains two molecules. The mononuclear units are linked into a chain structure along the b axis by intermolecular N-HÁ Á ÁS hydrogen bonds and weakstacking interactions between the pyridine rings [centroid-centroid = 3.758 (3) A ˚].
