摘    要:利用8-羟基喹啉原位反应,通过溶剂热方法制备出3种新颖的d~(10)配合物[M_2(HL)_3]NO_3·H_2O (M=Cd (1),Zn (2,3)),H_2L为1,1-(7,7′-二-(8-羟基喹啉))。单晶结构表明,3种配合物有着相同的带正电荷的结构单元[M_2(HL)_3]~+,但由于客体分子所处空间位置的不同表现为不同的空间结构,配合物1和3结晶于六方晶系(P6_3/m),配合物2结晶于三方晶系(R3)。中心金属离子以六配位的模式与来自HL-配体上的3个氧原子和3个氮原子形成一个轻微扭曲的八面体几何构型。存在于HL-配体与客体分子(NO_3~-,H_2O)间大量的弱作用力在结构空间堆积上起到了重要的作用。3种配合物均具有良好的热稳定性和绿色荧光发射性质。同时,通过从配合物1中提取出原位生成的配体H_2L,首次报道了其蓝色荧光发射性质。

关 键 词:d10配合物  原位反应  晶体结构  弱作用  荧光性质

Abstract:Three novel d10 complexes[M2(HL)3] NO3·H2O (M=Cd (1), Zn (2, 3), H2L=7,7''-(ethane-1,1-diyl)diquinolin-8-ol) have been synthesized under solvothermal conditions. Single crystal X-ray diffraction analysis reveals that the complexes have the same coordination positive charged unit,[M2(HL)3]+, but different lattice structures due to the different places of the guest molecules. Complexes 1 and 3 crystallize in hexagonal system (P63/m) and complex 2 crystallizes in trigonal system (R3). The metal ions are six-coordinated with three oxygen atoms and three nitrogen atoms of three HL- ligands, presenting a slightly distorted octahedron geometry. There are abundant weak interactions between HL- ligands and guest molecule (NO3- and H2O), which play a vital role in the form of the crystal packing. These complexes show good thermal stabilities and exhibit green fluorescence. Further, the fluorescence of ligand H2L extracted from the complex 1 has also been studied firstly and blue light emission of it was observed.
Keywords:d10 complexes  in situ reaction  crystal structures  weak interaction  luminescent properties
