4,4'-Bipyridine cocrystallizes with 3-hydroxy-2-naphthoic acid in a 1:2 ratio to give a centrosymmetric three-component supramolecular adduct, namely 3-hydroxy-2-naphthoic acid-4,4'-bipyridine (2/1), C11H8O3.0.5C10H8N2, in which 4,4'-bipyridine is located on an inversion center. The pyridine-carboxylic acid heterosynthon generates an infinite one-dimensional hydrogen-bonded chain via pi-pi interactions between naphthyl and 4,4'-bipyridine groups. The one-dimensional chains are further assembled into a three-dimensional network by weak C-H...pi interactions between pyridyl and naphthyl rings, and C-H...O interactions between 3-hydroxy-2-naphthoic acid molecules.
4,4'-联吡啶与3-羟基-2-萘甲酸以1:2的比例共结晶，形成一种中心对称的三组分超分子加合物，即3-羟基-2-萘甲酸-4,4'-联吡啶(2/1)，C11H8O3·0.5C10H8N2，其中4,4'-联吡啶位于一个反演中心上。吡啶-羧酸杂合成通过萘基和4,4'-联吡啶基团之间的π-π相互作用产生无限的一维氢键链。一维链通过吡啶基和萘基环之间的弱C-H…π相互作用以及3-羟基-2-萘甲酸分子之间的C-H…O相互作用进一步组装成三维网络。
