Abstract Co-crystals formed between anthranilic acid and each of 4,4′-bipyridine (1), 1,2-trans-1,2-bis(4-pyridyl)ethene (2) and 1,2-bis(4-pyridyl)ethane (3) have been formed from solutions containing 2:1 stoichiometric quantities of the reagents. Each structure features a centrosymmetric three-molecule aggregate mediated by O—H…N(pyridyl) hydrogen bonds indicating the robustness of the seven-membered {…HOCO…HCN} heterosynthon. The structures of (1)–(3) are isomorphous whereby the three…
