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。
Synthesis and characterization of a complex [CdL (H2O) (NO3)] NO3 · CH3COCH3 (1) (L = N-methyl N-phenyl-2- (8-quinolinyloxy) acetamide ). In complex 1, the metal cadmium ions adopt a distorted octahedral coordination configuration. One oxygen atom and two nitrogen atoms from ligand L, two oxygen atoms from two nitrates, and one oxygen atom from a coordination water molecule are coordinated to the central cadmium ion. The complex forms a one-dimensional chain structure along the a-axis through the O-H ... O hydrogen bonding between molecules. Ligand L and complex 1 in acetonitrile solution both have fluorescence emission at 390 nm, but the fluorescence intensity of the complex is much lower than that of the ligand.
