合成了配合物{[Cu(L)(OAc)]·Me OH}n(1)和[Zn(L)(OAc)]n(2)(HL为喹啉-8-甲醛缩异烟肼),并通过单晶X射线衍射、元素分析、红外光谱表征了结构。单晶衍射结果表明,除了结晶溶剂不同,2个配合物结构类似。每个配合物中,中心金属离子与来自烯醇化脱质子配体L-的2个O原子和1个N原子,1个单齿配位的醋酸根和相邻配体4-吡啶N原子配位,形成一维链状结构。但配合物中金属离子的配位构型分别为扭曲的四方锥和三角双锥。在360 nm紫外光激发下,甲醇溶液中配合物2在510 nm左右有很强的荧光发射,这是由锌离子配位荧光增强效应所导致。
The complexes {[Cu (L) (OAc)] · MeOH} n (1) and [Zn (L) (OAc)] n (2) were synthesized using HL as quinoline-8-carboxaldehyde isoniazid , And the structure was characterized by single crystal X-ray diffraction, elemental analysis and infrared spectroscopy. The results of single crystal diffraction show that the structures of the two complexes are similar except for the crystallization solvents. In each complex, the central metal ion interacts with two O atoms and one N atom from the enolized deprotonated L-ligand, one monodentate acetate and the adjacent ligand 4-pyridine N atom Bit, forming a one-dimensional chain structure. However, the complex metal ions in the configuration were twisted quadrilateral cone and triangular double cone. Under the excitation of 360 nm ultraviolet light, the complex 2 in methanol solution has a strong fluorescence emission at about 510 nm, which is caused by the fluorescence enhancement effect of zinc ion coordination.
