Hydrogen-bonded zigzag chains in 2,2'-dithiodibenzoic acid-1,3-di-4-pyridylpropane (1/1).
The title 1:1 cocrystal, C(14)H(10)O(4)S(2).C(13)H(14)N(2) or H(2)L.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...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.
