Abstract:  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(μ2-acetato-O,O)(μ2-acetato-O,O’)}2] (1), and [Zn2L2Cl2] (2) respectively Complex (1) 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 (2) is a dinuclear zinc compound, which possesses a two-fold rotation axis. In (2), 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.
