Abstract
Abstract Two organic co-crystals namely, 4,4′-bipyridine-bis(N-phenylanthranilic acid) ( 1 ) and 4,4′-bipyridinium bis(3-carboxypyridine-2-carboxylate) ( 2 ) have been synthesized and studied by FT-IR, TGA/DTA, and single crystal XRD studies. The crystal system of co-crystal 1 is triclinic with space group P1 and Z = 4 and that of co-crystal 2 is monoclinic with space group P2 1 /n and Z = 2. Intermolecular hydrogen bonds, O H⋯N, with graph set designator D 2 2 (10) play a vital role in the formation of the co-crystal 1 . Intramolecular hydrogen bond S(6) is also present in 1 and there is no π–π interaction. Whereas in co-crystal 2 , the intermolecular hydrogen bonds N H⋯N with graph set designator D 2 2 (12), O H⋯O with graph set designator D, and the π–π interactions together play a major role in stabilizing the structure.
