In the title compound, [Cu(C16H11N3O2S2)(C5H5N)]n, the CuII atom displays a square-pyramidal CuN2O3 coordination geometry with strong elongation in the vertex direction. The hydrazone molecule is coordinated to the CuII atom in a tridentate manner in the enolic form, creating five- and six-membered chelate metallarings. The pyridine molecule completes the square-planar base of the copper coordination environment. The crystal structure displays zigzag polymeric Cu-O-Cu chains along . Several weak - interactions between benzothiazole rings were found in the same direction [centroid-centroid distances = 3.7484 (16), 3.7483 (16), 3.6731 (17) and 3.7649 (17) Å].
