Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="chmetcnv"> Reactions of the tridentate Schiff base, 4-bromo-2-[(2-methylaminoethylimino)methyl]phenol with zinc acetate and zinc chloride, afford two polynuclear zinc complexes, [Zn{ZnL(μ<sub>2</sub>-acetato-<i style="">O</i>,<i style="">O</i>)(μ<sub>2</sub>-acetato-<i style="">O</i>,<i style="">O’</i>)}<sub>2</sub>] (<b>1</b>), and [Zn<sub>2</sub>L<sub>2</sub>Cl<sub>2</sub>] (<b style="">2</b>) respectively Complex (<b style="">1</b>) is a centrosymmetric trinuclear zinc compound, in which the two terminal Zn atoms are five-coordinate in a distorted square-pyramidal geometry, while the central Zn atom is six-coordinate in an octahedral geometry. Complex (<b style="">2</b>) is a dinuclear zinc compound, which possesses a two-fold rotation axis. In (<b style="">2</b>), one Zn atom is four-coordinate in a tetrahedral geometry, and the other one is six-coordinate in an octahedral geometry. The antibacterial activities of the Schiff base and the two complexes have also been tested. <b style=""></b> </smarttagtype>
