| 摘 要： | 合成并通过单晶衍射、元素分析及红外光谱表征了配合物[Ag2（HL）（NO3）2]n（1）的结构（HL为3-乙基-2-乙酰吡嗪缩4-苯基氨基脲）。单晶衍射结果表明，配合物1中，HL作为中性四齿配体连接2个Ag（I）中心，其中一个Ag（I）中心与HL配体中的ON2供体（羰基O，亚胺N和吡嗪N1原子）和2个单齿硝酸根配位，构成扭曲的四方锥配位构型；而另一个Ag（I）离子与1个单齿硝酸根，1个双齿硝酸根和HL配体中的吡嗪N4原子配位，形成扭曲平面正方形配位构型。另外，相邻的Ag（I）离子通过桥联的硝酸根离子相互连接形成二维层状结构；此外，配合物1与DNA的相互作用强于配体。

| Abstract: | The title complex[Ag2(HL)(NO3)2]n (1) (HL=1-(3-ethylpyrazin-2-yl)ethylidene-4-phenylsemicarbazide) has been synthesized and characterized by single crystal X-ray diffraction, elemental analysis and IR spectroscopy. X-ray diffraction analysis results show that in 1, HL acts as a neutral tetradentate ligand to connect with two Ag(I) centers, one of which adopts a distorted square pyramid coordination geometry involving one HL ligand with ON2 donor set (carbonyl O, imine N, and pyrazine N1 atoms) and two monodentate nitrate anions; while the other one is four-coordinated with one monodentate nitrate anion, one bidentate nitrate anion and pyrazine N4 atom, thus giving a planar square coordination geometry. Adjacent Ag(I) ions are further connected by bridged nitrate anions to form a 2D framework; Moreover, the fluorescence spectra indicate that the interaction of the complex 1 with DNA is stronger than that of the ligand HL. |
