含喹啉氧基乙酰胺型配体的锌配合物的合成、晶体结构及荧光性质(英文)

Zinc Complex with Acetamide Type Ligand Bearing Quinolinyloxy Unit:Synthesis,Crystal Structure and Fluorescence Spectra

合成并通过单晶衍射表征了一个配合物[ZnL(NO3)2].CH3CN(1,L=N-(1-萘基)-2-(8-喹啉氧基)乙酰胺)。在配合物1中,金属锌离子采取扭曲的四方锥的配位构型。来自配体L的1个氧原子,2个氮原子及来自2个硝酸根的2个氧原子和中心锌离子配位。配合物通过分子间的N-H…O氢键作用构筑成沿a轴的链状结构。乙腈溶液中配合物在414.8 nm处有强荧光发射。

A complex,[ZnL（NO3）2]·CH3CN（1,L=N-（naphthalen-1-yl）-2-（quinolin-8-yloxy）acetamide）,was synth-esized and characterized by X-ray diffraction.In complex 1,the Zn2＋ center,possessing a coordination geometry closer to a distorted square-pyramidal,coordinates with one nitrogen atom from the L ligand and four oxygen atoms,two of which are from L ligand and the others are from two nitrate ligands,respectively.In the crystal,intramolecular N-H…O hydrogen bonds link the molecules into chains along the a axis.In CH3CN solution,the complex 1 exhibits strong emission band at 414.8 nm.CCDC： 848089.
