摘要

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.
