Abstract

Co-crystals of 4,4′-bipyridine and 4-hydroxybenzoic acid (1 ∶ 2) show synthon polymorphism with the former being more stable. A 2 ∶ 1 co-crystal is pseudopolymorphic within the same structural landscape with the structural roles of the two bipyridine N-atoms being distinct, as evidenced by mimicry by 4-phenylpyridine.
