摘要：

Three complexes, [CuLCl2]center dot CH3CN (1), [CuLBr2]center dot CH3CN (2) and [ZnL(NO3)(2)]center dot CH3CN (3) (L =2-(5-chloroquinolin-8-yloxy)-1-(pyrrolidin-1-yl)ethanone), were synthesized and characterized by X-ray diffraction. In each of complexes 1 and 2, the five-coordinated COO ion is in a distorted tetragonal pyramid with a NO2 donor set from one ligand L and two halide anions. However, the Zn(II) ion in complex 3 is surrounded by one tridentate ligand L and two nitrate anions, one of which is monodentate and the other is bidentate, thus giving distorted octahedral coordination geometry. In CH3CN solution, complexes 1 and 2 exhibit similar peak at 410 nm as that of the ligand L, while with a decrease of the fluorescence intensity. However, the emission band of complex 3 red-shifts to 430 nm because of energy transferring from the ligand L to the Zn (II) ion. CCDC: 1474712, 1; 1474713, 2; 1474714, 3.
