作为相互识别的结果,(±)-2,2′-二羟基-1,1′-联萘酚可与4,4′,6,6′-四甲基-2,2′-联嘧啶、1,2-双(4-吡啶)乙烷、反式-1,2-双(4-吡啶)乙烯、4,4′-联吡啶-N,N′-双氧化物及双-2-吡啶基甲酮等多种含氮化合物分别形成外形良好的共晶化合物1,2,3,4及5.本文对5个共晶化合物的晶体结构进行了分析.结果表明,由于这些晶体结构中都存在强的O—H…O,N—H…O和O-H…N氢键,晶体可稳定存在.在这5个共晶中,各组分依靠强氢键形成无限一维极性排列.由于C-H…π和π…π等弱作用对晶体结构的形成产生很大作用并能影响到晶体骨架结构,因此,在这些弱作用的影响下,共晶1,2和5展现出二维层状结构,而共晶3和4呈现为三维超分子结构.

As a result of mutual recognition,( ± )-2,2′-dihydroxy-1,1 '-binaphthyl(binol) and various N-containing compounds 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 1-5,respectively.The crystal structures of the co-crystals were elucidated and all stabilized by O-H…O,N-H…O and O-H…N hydrogen bonds.In co-crystals 1-5,the components form an infinite one-dimensional( 1 D) polar array.The weak C-H…π and π…π interactions have great role in the crystals 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.
