The title 1:1 cocrystal, C14H10O4S2 center dot C13H14N2 or H2L.bpp, has the two components connected by O-H center dot center dot center dot N hydrogen bonds to generate a one-dimensional zigzag chain running along the crystallographic a direction. These chains are further stacked into a three-dimensional supramolecular network by weak C-H center dot center dot center dot O and C-H center dot center dot center dot pi contacts. Comparison of the structural differences with previous findings suggests that deprotonated forms, hydrogen-bonding sites and flexible ligand conformations become significant factors that influence the topological arrangement and binding stoichiometry of the resulting cocrystals.
