摘　　要：合成并通过单晶衍射表征了5个配合物[Cu LCl2]·CH3COCH3(1)、[Zn LCl2]·CH3COCH3(2)、[Zn L(NO3)2]·0.5CH3COCH3(3)、[Ag L2]Cl O4(4)和[Ag L2]BF4(5)(L=2-(5-氯-8-喹啉氧基)-1-(吡咯烷-1-基)乙酮)。配合物1和2同构,五配位的中心金属离子采取扭曲的四方锥配位构型,与来自配体L的2个氧原子和1个氮原子及2个氯离子配位。而在配合物3中,锌离子与1个三齿配位的配体L,1个单齿配位的硝酸根和1个双齿配位的硝酸根配位,配位构型为扭曲的八面体。配合物4和5中,中心金属与配体的比例为1∶2。银离子与2个三齿配位的配体L配位,采取扭曲的八面体配位构型。乙腈溶液中,配合物1、2、4和5在410 nm处的最大荧光发射峰与配体L相似。而配合物3由于配体到锌离子之间的能量转移,最大荧光发射峰红移至430 nm。Five complexes,[Cu LCl2]·CH3COCH3（1）,[Zn LCl2]·CH3COCH3（2）,[Zn L（NO3）2]·0.5CH3COCH3（3）,[Ag L2]Cl O4（4） and [Ag L2]BF4（5）（L =2-（5-chloroquinolin-8-yloxy）-1-（pyrrolidin-1-yl）ethanone）,were synthesized and characterized by X-ray diffraction.Complexes 1 and 2 are isostructural,and in each of them the fivecoordinated metal ion is in a distorted tetragonal pyramid with a NO2 donor set from one ligand L and two chloride anions.However,the Zn （Ⅱ） ion in complex 3 is coordinated with one tridentate ligand L,one monodentate and one bidentate nitrate anions,giving a distorted octahedral coordination geometry.The structures of 1~3 are quite similar as those of the acetonitrile solvates derived from the same ligand L and metal salts.By contrast,the ratio of the metal ion and ligand L is 1∶2 in complexes 4 and 5,the central Ag（Ⅰ） ion in each complex is six-coordinated with two independent ligands with N2 O donor set,thus possesses a distorted octahedral coordination geometry.In CH3 CN solution,the emission spectra of complexes 1,3,4 and 5 exhibit similar peak at410 nm as the ligand L.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.
