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.
