由氢键和π-π相互作用形成的反-丁烯二酸和反-1,2-二(4-吡啶基)乙烯超分子

Trans-fumarate Anions and Trans-1,2-di(4-pyridyl) ethylene Cations Super-molecule Formed Through Hydrogen Bonding and π-π Interaction

氢键和π-π弱相互作用力在形成超分子结构中起着非常重要的作用.本文中反-丁烯二酸和反-1,2-二(4-吡啶基)乙烯通过氢键和π-π弱相互作用形成超分子.去质子化的反-丁烯二酸阴离子和质子化的反-1,2-二(4-吡啶基)乙烯通过N-H…O氢键形成一维链状结构,通过吡啶环之间的π-π弱相互作用形成二维的层状结构,通过相邻层之间的C-H…O氢键形成三维的结构,所以氢键和π-π相互作用对此超分子的形成起了决定性的作用.

Hydrogen bond and π-π interactions play an important role in the forming process and structure of super-molecules.It is stated in this article that deprotonated trans-fumarate anions and protonated trans-1,2-di(4-pyridyl)ethylene cations form a one-dimensional chain through N-H…O hydrogen bond,followed by a two-dimensional layer structure which is generated by π-π weak interaction.A three-dimension super-molecular structure is finally obtained by means of C-H…O hydrogen bonding weak interaction.
