4，4 ′-联吡啶与4-羟基苯甲酸（1：2）的共晶显示出多晶型，其中联吡啶的稳定性更高。答2：1共晶是假多晶的，在相同的结构景观与两个联吡啶N-原子的结构作用是不同的，证明由4-苯基吡啶模仿。
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.
