Abstract: As a result of mutual recognition, (±)-2,2’-dihydroxy-1,1’-binaphthyl (binol) and various aromatic amines and its derivatives including 4,4’,6,6’-tetramethyl-2,2’-bipyrimidine (4-tmpi), 1,2-bis(4-pyridyl)ethane (4-bpa), trans-1,2-bis(4-pyridyl)ethene (4-bpe) 4,4’-bipyridine-N,N’-dioxide (4-bpo), and di-2-pyridyl ketone (4-dpk) formed well-defined co-crystals 1, 2, 3, 4 and 5, respectively. The crystal structures of these co-crystals were elucidated and are all stabilized by O-H???O, N-H???O and O-H???N hydrogen bonds. In 1-5, the components form an infinite one-dimensional (1D) polar array. The weak C-H???π and π???π interactions have great role in the crystal and influence the architecture of the crystal structure. So, the co-crystals 1, 2, and 5 exhibit two-dimensional (2D) sheet structures, while the co-crystals 3 and 4 display three-dimensional (3D) supramolecular architectures.

Key words: Co-crystal, 2,2′-Dihydroxy-1,1′-binaphthyl, Hydrogen bond
