Abstract: | Cocrystallization of 2,2′‐dithiodibenzoic acid with isonicotinohydrazide from methanol solution yields the 1:2 cocrystal 2,2′‐dithiodibenzoic acid–isonicotinohydrazide (1/2), C14H10O4S2·2C6H7N3O. The component molecules are linked by intermolecular O—H...N, N—H...O, N—H...N and C—H...O hydrogen bonds into layers running parallel to the (010) plane, and these layers are further linked into a three‐dimensional framework structure by means of weak aromatic π–π stacking interactions. As a potential cocrystallization agent, isonicotinohydrazide may be used for effective and versatile synthetic supramolecular strategies utilizing hydrogen bonding of specific molecular building blocks. |
