| 摘 要： | 合成并结构表征了一种新型的线性三核锌(II)配合物，{ZnL(OAc)]2Zn}∙CH3COCH3（H2L：乙二氧双(5-溴-2-羟基苯亚甲基胺)）。X-射线结构表明配合物中三个锌(II)离子配位到了两个四齿的L2-单元和两个桥联的的乙酸根基团。围绕两端的Zn(1) 或 Zn(1)#1原子形成了扭曲的四方锥配位几何体，围绕中心Zn(2) 原子构成了一个稍微扭曲的八面体配位结构。同时，观察到锌(II)配合物能发出蓝绿色荧光，其最大发射波长为464 nm。

| Abstract: | A novel linear trinuclear zinc(II) complex, {ZnL(OAc)]2Zn}·CH3COCH3 (H2L: ethylenedioxybis(5‐bromo‐2‐ hydroxybenzylideneamino)), has been synthesized and structurally characterized. X‐ray crystal structure of the complex reveals that three zinc(II) ions are coordinated by two tetradentate L2? units and two acetate ions acting as bridging groups. The coordination geometry around the terminal Zn(1) or Zn(1)#1 atom approaches a distorted square pyramid. The coordination sphere of the central Zn(2) atom constitutes a slightly distorted octahedral geometry. The blue‐green emission from the zinc(II) complex can be observed, where the maximum emission wavelength is at 464 nm. |
