Abstract

The NiII atom in the title complex, [Ni(C11H13N3OS)(C5H5N)], exists within a square-planar N3O donor set provided by N,N′,O atoms of the dianionic tridentate ligand and a pyridine N atom. The maximum deviation from the ideal geometry is seen in the N—Ni—N five-membered chelate bite angle of 83.28 (12)°. The pyridine mol­ecule forms a dihedral angle of 44.43 (6)° with the N3O donor set. Supra­molecular stacks along the a axis mediated by alternating π–π inter­actions between the pyridine and five- [centroid–centroid distance = 3.4784 (16) Å] and six-membered [3.4633 (17) Å] chelate rings, feature in the crystal packing.
