酰胺型配体的镍(Ⅱ)和锌(Ⅱ)配合物的合成、晶体结构及荧光性质

摘要

Two new complexes,[M(nbqa)(NO3)(H2O)2]NO3 (M=Ni,1; Zn,2; nbqa=N-benzyl-2-(quinolin-8-yloxy)acetamide) were synthesized and characterized by elemental analysis,IR spectroscopy,UV spectroscopy and X-ray diffraction.Both in complexes 1 and 2,the metal ions are in distorted octahedral geometry with the donor centers of two O atoms and one N atom from the ligand nbqa,two O atoms from two water molecules and one O atom from one nitrate anion.In CH3CN solution,the ligand nbqa exhibits emission band at 390 nm.However,the complex 2 exhibits stronger emission band at 430 nm.CCDC:838270,1; 838271,2.%合成并通过单晶衍射表征了配合物[M(nbqa)(NO3)(H2O)2]NO3(M=Ni,1;Zn,2;nbqa=N-苄基-2-(8-喹啉氧基)乙酰胺).在配合物1和2中,金属离子采取扭曲的八面体配位构型.来自配体nbqa的1个氧原子和2个氮原子,来自硝酸根的1个氧原子及来自2个配位水分子的氧原子和中心金属离子配位.乙腈溶液中配合物2在430 nm有强荧光发射.
