| 摘要: 合成并通过单晶衍射表征了一个配合物[CdL(H2O)(NO3)]NO3·CH3COCH3 (1)(L=N-甲基N-苯基-2-(8-喹啉氧基)乙酰胺)。在配合物1中，金属镉离子采取扭曲的八面体配位构型。来自配体L的1个氧原子和2个氮原子，2个硝酸根的2个氧原子及配位水分子的1个氧原子与中心镉离子配位。配合物通过分子间的O-H…O氢键作用构筑成沿a轴的一维链状结构。乙腈溶液中配体L和配合物1均在390 nm有荧光发射，但配合物的荧光强度要远低于配体。 |

| Abstract: [CdL(H2O)(NO3)]NO3·CH3COCH3(1) (L=N-methyl-N-phenyl-2-(quinolin-8-yloxy)acetamide), was synth-esized and characterized by X-ray diffraction. In complex 1, the Cd(Ⅱ) center is coordinated with two O atoms and one N atom from one ligand L, two O atoms from two mono-dentate nitrate anions and one O atom from one water molecule, possessing a distorted octahedral coordination geometry. In the crystal, intramolecular O-H…O hydrogen bonds between the coordinated water molecules and free nitrate O atoms link the complexes into chains along the a axis. In CH3CN solution, both ligand L and complex 1 exhibit emission band at 390 nm. However, the emission intensity of 1 is much lower than that of the ligand L. CCDC: 958121. |
