Abstract: The title complex, C₇H₆N₂S·C₁₇H₁₃NO₃, consists of donor and acceptor -stacks in the alternating A-D-D'-A' pattern, through parallel displaced interactions, with a mean interplanar distance of 3.50  (3)  Å. The complete three-dimensional supramolecular arrangement is achieved by both N-HO and C-HX (X = O, aryl) hydrogen-bonding interactions, which define an ADD'A' hydrogen-bonded tetramer, among other supramolecular structures.
