摘要
合成了锌（Ⅱ）与杂环碱[2，2－联吡啶（bpy）、1，10－邻氮二菲（phen）]和苯乙酸（HPAC）二种混配合物，并用元素分忻、摩尔电导、红外、1H核磁共振等手段进行了表征。配合物的组成为：Zn（bpy）2（PAC）（HPAC）（NO3）和Zn（phen）2（PAC）（H2O）（NO3）。配合物芳环之间有相互堆积作用，且堆积作用大小与芳环的匹配性有关。
Two complexes of the Zn2+ -PAC-A (A-2, 21-bipyridine, 1, 10-phenanthroline)system had been synthesized and characterized by elemental analyses, molar conductance, infrared spectroscopy and HNMR techniques. The results showed that the complexes were defined into two types: Zn (bpy)2 (PAC) (HPAC) (NO3) and Zn (phen)2 (PAC) (H2O)(NO3). The stacking interactions of the interligand aromatic rings in the Zn2+ -PAC- -A system had been confirmed by 1HNMR. The stacking interaction of aromatic rings depends on the fit of aromatic ring with a trend as follows: 2, 21-bipyridine>1, 10-phenanthroline.
