Abstract

A novel linear trinuclear zinc(II) complex, {[ZnL(OAc)]~2~Zn}·CH~3~COCH~3~ (H~2~L: 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 L^2−^ 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.
