摘要: L-(-)-α-苯乙胺与消旋的类立方烷结构2-萘甲酸二聚体相互作用形成铵盐,其晶体结构表明,L-(-)-α-苯乙胺与类立方烷结构2-萘甲酸二聚体作用形成的铵离子通过氢键N2A-HN2B…O5A和N1A-HN1A…O3A与类立方烷结构2-萘甲酸二聚体结合在一起.同时类立方烷结构2-萘甲酸二聚体的两个对映异构体之间也存在分子间氢键O1A-H1AA…O6A和O1B-H1AB…O6B.这些氢键将类立方烷结构2-萘甲酸二聚体的两个对映异构体连在同一个晶胞中,呈现两条分子链状堆积.

关键词: L-(-)-α-苯乙胺, 类立方烷结构2-萘甲酸二聚体, C2对称性

Abstract: L-(-)-α-Phenyl ethylamine was reacted with cubane-like dimer of carboxylic 2-naphthoate to afford L-(-)-α-phenyl ethylammonium cubane-like dimer of carboxylic 2-naphthoate with high yield.Crystal structural analysis demonstrates that the hydrogen bonding of N2A-HN2B…O5A and O1A-HN1A…O3A are responsible for the crystal packing,in which N2A-HN2B…O5A connects L-(-)-α-phenyl ethylammonium cation and cubane-like dimer of carboxylic 2-naphthoate.Intermolecular hydrogen bonding of O1A-H1AA…O6A and O1B-H1AB…O6B directs the assembly of two enatiomers of cubane-like dimer of carboxylic 2-naphthoate acid.

Key words: L-(-)-α-phenyl ethylamine, cubane-like dimer of carboxylic 2-naphthoate acid, C2 symmetry
