Hydrogen‐bonded zigzag chains in 2,2′‐dithiodibenzoic acid–1,3‐di‐4‐pyridylpropane (1/1)

The title 1:1 cocrystal, C₁₄H₁₀O₄S₂·C₁₃H₁₄N₂ or H₂L·bpp, has the two components connected by O—H...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...O and C—H...π 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.
